USB: use generic platform driver on ath79
The ath79 usb driver doesn't do anything special and is now converted to the generic ehci and ohci driver. This was tested on a TP-Link TL-WR1043ND (AR9132) Acked-by: Gabor Juhos <juhosg@openwrt.org> CC: Imre Kaloz <kaloz@openwrt.org> CC: linux-mips@linux-mips.org CC: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
