This function is clearly architecture specific code, not board specific code. The only difference from the previous arm arch_lmb_reserve() is the extra reservation of 16k of memory below the stack bottom, rather than the 4k. The common code now also uses 16k alignment. Remove this custom implementation, as it now behaves exactly as the common code.
