staging: octeon-usb: use a single .h file 

Merge USBC and USBN register definitions into a single header
file. Although all HW definitions are purely internal to the driver,
it's better to keep them separate due to the large size of the file.

/**
* struct cvmx_usbnx_usbp_ctl_status_s
* @txrisetune: HS Transmitter Rise/Fall Time Adjustment
* @txvreftune: HS DC Voltage Level Adjustment
* @txfslstune: FS/LS Source Impedence Adjustment
* @txhsxvtune: Transmitter High-Speed Crossover Adjustment
* @sqrxtune: Squelch Threshold Adjustment
* @compdistune: Disconnect Threshold Adjustment
* @otgtune: VBUS Valid Threshold Adjustment
* @otgdisable: OTG Block Disable
* @portreset: Per_Port Reset
* @drvvbus: Drive VBUS
* @lsbist: Low-Speed BIST Enable.
* @fsbist: Full-Speed BIST Enable.
* @hsbist: High-Speed BIST Enable.
* @bist_done: PHY Bist Done.
* Asserted at the end of the PHY BIST sequence.
* @bist_err: PHY Bist Error.
* Indicates an internal error was detected during
* the BIST sequence.
* @tdata_out: PHY Test Data Out.
* Presents either internaly generated signals or
* test register contents, based upon the value of
* test_data_out_sel.
* @siddq: Drives the USBP (USB-PHY) SIDDQ input.
* Normally should be set to zero.
* When customers have no intent to use USB PHY
* interface, they should:
* - still provide 3.3V to USB_VDD33, and
* - tie USB_REXT to 3.3V supply, and
* - set USBN*_USBP_CTL_STATUS[SIDDQ]=1
* @txpreemphasistune: HS Transmitter Pre-Emphasis Enable
* @dma_bmode: When set to 1 the L2C DMA address will be updated
* with byte-counts between packets. When set to 0
* the L2C DMA address is incremented to the next
* 4-byte aligned address after adding byte-count.
* @usbc_end: Bigendian input to the USB Core. This should be
* set to '0' for operation.
* @usbp_bist: PHY, This is cleared '0' to run BIST on the USBP.
* @tclk: PHY Test Clock, used to load TDATA_IN to the USBP.
* @dp_pulld: PHY DP_PULLDOWN input to the USB-PHY.
* This signal enables the pull-down resistance on
* the D+ line. '1' pull down-resistance is connected
* to D+/ '0' pull down resistance is not connected
* to D+. When an A/B device is acting as a host
* (downstream-facing port), dp_pulldown and
* dm_pulldown are enabled. This must not toggle
* during normal opeartion.
* @dm_pulld: PHY DM_PULLDOWN input to the USB-PHY.
* This signal enables the pull-down resistance on
* the D- line. '1' pull down-resistance is connected
* to D-. '0' pull down resistance is not connected
* to D-. When an A/B device is acting as a host
* (downstream-facing port), dp_pulldown and
* dm_pulldown are enabled. This must not toggle
* during normal opeartion.
* @hst_mode: When '0' the USB is acting as HOST, when '1'
* USB is acting as device. This field needs to be
* set while the USB is in reset.
* @tuning: Transmitter Tuning for High-Speed Operation.
* Tunes the current supply and rise/fall output
* times for high-speed operation.
* [20:19] == 11: Current supply increased
* approximately 9%
* [20:19] == 10: Current supply increased
* approximately 4.5%
* [20:19] == 01: Design default.
* [20:19] == 00: Current supply decreased
* approximately 4.5%
* [22:21] == 11: Rise and fall times are increased.
* [22:21] == 10: Design default.
* [22:21] == 01: Rise and fall times are decreased.
* [22:21] == 00: Rise and fall times are decreased
* further as compared to the 01 setting.
* @tx_bs_enh: Transmit Bit Stuffing on [15:8].
* Enables or disables bit stuffing on data[15:8]
* when bit-stuffing is enabled.
* @tx_bs_en: Transmit Bit Stuffing on [7:0].
* Enables or disables bit stuffing on data[7:0]
* when bit-stuffing is enabled.
* @loop_enb: PHY Loopback Test Enable.
* '1': During data transmission the receive is
* enabled.
* '0': During data transmission the receive is
* disabled.
* Must be '0' for normal operation.
* @vtest_enb: Analog Test Pin Enable.
* '1' The PHY's analog_test pin is enabled for the
* input and output of applicable analog test signals.
* '0' THe analog_test pin is disabled.
* @bist_enb: Built-In Self Test Enable.
* Used to activate BIST in the PHY.
* @tdata_sel: Test Data Out Select.
* '1' test_data_out[3:0] (PHY) register contents
* are output. '0' internaly generated signals are
* output.
* @taddr_in: Mode Address for Test Interface.
* Specifies the register address for writing to or
* reading from the PHY test interface register.
* @tdata_in: Internal Testing Register Input Data and Select
* This is a test bus. Data is present on [3:0],
* and its corresponding select (enable) is present
* on bits [7:4].
* @ate_reset: Reset input from automatic test equipment.
* This is a test signal. When the USB Core is
* powered up (not in Susned Mode), an automatic
* tester can use this to disable phy_clock and
* free_clk, then re-eanable them with an aligned
* phase.
* '1': The phy_clk and free_clk outputs are
* disabled. "0": The phy_clock and free_clk outputs
* are available within a specific period after the
* de-assertion.
