ARM: OMAP3: Fix hardware detection for omap3630 when booted with device tree
SoC family definitions at the moment are reactive to board needs
as a result, beagle-xm would matchup with ti,omap3 which invokes
omap3430_init_early instead of omap3630_init_early. Obviously, this is
the wrong behavior.
With clock node dts conversion, we get the following warnings before
system hangs as a result and 3630 based platforms fails to boot
(uart4 clocks are only present in OMAP3630 and not present in
OMAP3430):
...
omap_hwmod: uart4: cannot clk_get main_clk uart4_fck
omap_hwmod: uart4: cannot _init_clocks
WARNING: CPU: 0 PID: 1 at arch/arm/mach-omap2/omap_hwmod.c:2434
_init+0x6c/0x80()
omap_hwmod: uart4: couldn't init clocks
...
WARNING: CPU: 0 PID: 1 at arch/arm/mach-omap2/omap_hwmod.c:2126
_enable+0x254/0x280()
omap_hwmod: timer12: enabled state can only be entered from
initialized, idle, or disabled state
...
WARNING: CPU: 0 PID: 46 at arch/arm/mach-omap2/omap_hwmod.c:2224
_idle+0xd4/0xf8()
omap_hwmod: timer12: idle state can only be entered from enabled state
WARNING: CPU: 0 PID: 1 at arch/arm/mach-omap2/omap_hwmod.c:2126
_enable+0x254/0x280()
omap_hwmod: uart4: enabled state can only be entered from
initialized, idle, or disabled state
So, add specific compatiblity for 3630 to allow match for Beagle-XM
platform.

ARM: dts: Add minimal DT support for DevKit8000
DevKit8000 is a beagle board clone from Timll, sold by
armkits.com. The DevKit8000 has RS232 serial port, LCD, DVI-D,
S-Video, Ethernet, SD/MMC, keyboard, camera, SPI, I2C, USB and
JTAG interface.
Add the basic DT support for devkit8000. It includes:
- twl4030 (PMIC)
- MMC1
- I2C1
- leds
