Revert "usb: gadget: fsl: Re-enable driver for ARM SoCs"

This reverts commit e0e8b6abe8c862229ba00cdd806e8598cdef00bb.

Turns out this breaks the build.  We had numerous reports of problems
from linux-next and 0-day about this not working properly, so revert it
for now until it can be figured out properly.

The build errors are:
	arm-linux-gnueabi-ld: fsl_udc_core.c:(.text+0x29d4): undefined reference to `fsl_udc_clk_finalize'
	arm-linux-gnueabi-ld: fsl_udc_core.c:(.text+0x2ba8): undefined reference to `fsl_udc_clk_release'
	fsl_udc_core.c:(.text+0x2848): undefined reference to `fsl_udc_clk_init'
	fsl_udc_core.c:(.text+0xe88): undefined reference to `fsl_udc_clk_release'
