I've looked more closely, and I think a good way to solve this would be
to revert or remove "ARM: at91: PIT: Convert to an early_platform_device",
and add declarations for the two global functions to
include/clocksource/at91.h and passing the interrupt number as an argument
to at91sam926x_pit_init.

I understand it's not the goal you had in mind here, but it's far simpler
and it gives me hope that we can eventually kill that early platform
code.
