In its current form, dcr_map() doesn't remember the base address you passed
it, which means you need to store it somewhere else. Rather than adding the
base to another struct it seems simpler to store it in the dcr_host_t.

This patch adds new dcr_map/dcr_read/dcr_write accessors for DCRs that
can be used by drivers to transparently address either native DCRs or
memory mapped DCRs. The implementation for memory mapped DCRs is done
after the binding being currently worked on for SLOF and the Axon
chipset. This patch enables it for the cell native platform
