FVP: Fix AArch32 stack functions to be ABI-compliant
plat_get_my_stack is called from C, so it can't expect argument
registers to be preserved. Stash registers temporarily onto the stack
instead.
plat_set_my_stack is called during early init, when there exists no
stack. Use any register other than argument registers to stash temporary
values.
