usb: gadget: at91_udc: Rework for multi-platform kernel support
cpu_is_at91xxx are a set of macros defined in mach/cpu.h and are here used
to detect the SoC we are booting on.
Use compatible string + a caps structure to replace those cpu_is_xxx tests.
Remove all mach and asm headers (which are now unused).
