It doesn't make sense to present option MFD_AT91_USART by default if
not building an AT91 kernel, as the drivers which depend on it are
not available.

As a side note, maybe it would make sense to have SPI_AT91_USART
select MFD_AT91_USART instead of depend on it, so that
MFD_AT91_USART could be hidden?
