Log Message:
Align sp to 8-byte boundary as required by EABI.

This is especially important for non-leaf functions; GCC optimizes codes
based on assumption that sp is aligned properly.

Mostly fix broken earmv5 userland compiled by GCC10 due to alignment
faults in ld.elf_so, where {ld,st}rd are used for [sp, #8x].

No regression for ATF is observed for earmv[67]{,hf}{,eb}.
