WIO I/O space base address
This register defines the starting address of WIO I/O space on a 64K
boundary. As the high halfword (16 bits) address lines of PCI
accesses match the WIOBASE[0:15], and if CFG[0] is set high, WIO
controller responds DEVSEL_ and TRDY_ to PCI bridge and issues
an I/O access cycle to WIO I/O devices.
