[PATCH] usb: gadget: fsl: Re-enable driver for ARM SoCs

[Joel Stanley]

The commit a390bef7db1f ("usb: gadget: fsl_mxc_udc: Remove the driver")
dropped the ARCH_MXC dependency from USB_FSL_USB2, leaving it depending
solely on FSL_SOC.

FSL_SOC is powerpc only; it was briefly available on ARM in 2014 with
commit cfd074ad8600 ("ARM: imx: temporarily remove CONFIG_SOC_FSL from
LS1021A"). Therefore the driver can no longer be enabled on ARM
platforms.

This appears to be a mistake as arm64's ARCH_LAERSCAPE and arm32
SOC_LS1021A SoCs use this symbol. It's enabled in these defconfigs:

arch/arm/configs/imx_v6_v7_defconfig:CONFIG_USB_FSL_USB2=y
arch/arm/configs/multi_v7_defconfig:CONFIG_USB_FSL_USB2=y
arch/powerpc/configs/mgcoge_defconfig:CONFIG_USB_FSL_USB2=y
arch/powerpc/configs/mpc512x_defconfig:CONFIG_USB_FSL_USB2=y

To fix, expand the dependencies so USB_FSL_USB2 can be enabled on the
ARM platforms, and with COMPILE_TEST.
