Add console command to access io space registers
Provide u-boot console functions to access IO space registers. A no
thrills implementation, accessing one register at a time.
For example:
boot > iod 80
0080: 00000094
boot > iod.w 80
0080: 0094
boot > iod.b 80
0080: 94
boot > iow.b 0x80 12
boot > iod 0x80
0080: 00000012
