adu: Add arugments for block size

Not all memory can be read with the default ADU block size of 8
bytes. Specifically cache-inhibited access to some MMIO regions such
as PCIe BAR spaces requires 4 byte accesses to avoid check stopping
the machine.

This patch adds library functions to read/write IO memory which takes
a block size argument and two new put/getmemio commands to allow a
specific block size to be specified from the command line.
