[PATCH 20/28] ARM: at91: sama5d2: reuse stack set-up by first stage

[Ahmad Fatoum <a.fatoum@xxxxxxxxxxxxxx>]

Stack is always set up to end of SRAM before PBL, either by ROM code or
by first stage bootloader, be it at91bootstrap or barebox in a later
commit, so no need to change the stack pointer again.
