Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16
bytes from the stack top. This is unnecessary as on ARM we have a stack
that decrements before storing values. Substracting this offset probably
goes back to the U-Boot version we forked from. Stop this now.

at91sama5_get_ddram_size() is despite the name specific to the
sama5d3 which it was added alongside of. sama5d4 board code continues
to use it, but accessing SAMA5D3_BASE_MPDDRC (0xffffea00) on
a sama5d4 should result in a Data Abort (Datasheet Figure 5-1)..
Fix this by giving at91sama5_get_ddram_size the mpddrc base
address as argument and migrate users to use one of two helpers
that specify the base address.

[afa: Sam didn't test this exact change, but tested the use
of the critical part: accessing a different register]

The code that configure the stack uses sama5d3 constants.
Fix this to use the proper sama5d4 constants.
Boot tested on sama5d4_xplained.

barebox_arm_reset_vector() is a global function but we never provided a
prototype anywhere. The prototypes differ for the different boards, so
to provide a common prototype we must harmonize them.
void barebox_arm_reset_vector(uint32_t r0, uint32_t r1, uint32_t r2)
Should be suitable for all boards.
