[PATCH RFC] ARM: at91: remove at91_register_uart_fns and headers

[Joachim Eastwood]

No AT91/AVR32 boards currently use at91_register_uart_fns so let's remove it.

The only other mach in the kernel that has a *_register_uart_fns function
is SA1100 so the demand for this functionality is not great.
