Subject: [PATCH] fix minor error about efi memory_present

Hi, 
   Function efi_memory_present_wrapper parameter start/end is physical address,
but function memory_present parameter is PFN, this patch converts physical
address to PFN.

  Signed-off-by: bibo, mao <bibo.mao@...el.com>

thanks
bibo,mao
