sbc8641d: Fix PCI mapping concepts
Rename _BASE to _BUS, as it's actually a PCI bus address, separate virtual and physical addresses into _VIRT and _PHYS, and use each appopriately. This makes the code easier to read and understand, and facilitates mapping changes going forward. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org>
