ARM: at91: make bootsource code generic to all SAMA5

While I couldn't find documentation, the BootROM of all of SAMA5D2, D3
and D4 populates R4 when calling next stage bootloader with information
about the booutsource. barebox PBL will pass along this information to
barebox proper, so add a generic initcall that sets the bootsource.
