sh: Support fixed 32-bit PMB mappings from bootloader.
This provides a method for supporting fixed PMB mappings inherited from
the bootloader, as an alternative to the dynamic PMB mapping currently
used by the kernel. In the future these methods will be combined.
P1/P2 area is handled like a regular 29-bit physical address, and local
bus device are assigned P3 area addresses.
