Well, we already have the CYGHWR_HAL_ARM_AT91 option that must be set
in the platform HAL to select the correct AT91 variant. This is used
in var_io.h to differentiate between different power-saving
devices. The same option should be used to select different sets of
PIO pin definitions. There's probably no need to do anything more
complicated.
Of course someone will have to type in all the pin definitions.
