lmb: do away with arch_lmb_reserve()
All of the current definitions of arch_lmb_reserve() are doing the
same thing -- reserve the region of memory occupied by U-Boot,
starting from the current stack address to the ram_top. Introduce a
function lmb_reserve_uboot_region() which does this, and do away with
the arch_lmb_reserve() function.
Instead of using the current value of stack pointer for starting the
reserved region, have a fixed value, considering the stack size config
value.
