cmd: Update the meminfo command to show the memory map

Browse Source 
U-Boot has a fairly rigid memory map which is normally not visible
unless debugging is enabled in board_f.c

Update the 'meminfo' command to show it. This command does not cover
arch-specific pieces but gives a good overview of where things are.
