1. Define all registers. These definitions are needed to support
the FCM driver for direct-connect NAND.
2. Repurpose lbc_read_reg() and lbc_write_reg() for use by localbus
attached device drivers. Use bus_space functions directly in the
lbc driver itself.
3. Be smarter about programming LAWs and mapping memory. The ranges
defined in the FDT are per bank (= chip select) and since we can
have up to 8 banks, we could easily use more than 8 LAWs or TLB
enrties when per-bank memory ranges need multiple LAWs or TLBs
due to alignment or size constraints.
We now combine all memory ranges into the fewest possible set of
contiguous regions and program the hardware for that. Thus, a
cleverly written FDT with 8 devices may still only need 1 LAW or
1 TLB entry. Note that the memory ranges can be assigned randomly
to the banks. We sort as we build to handle that.
4. Support the FCM when programming the OR register. This is mostly
for documention purposes as we do not have a way to define the
mode for a bank.
5. Remove Semihalf-ism: do not define DEBUG (only to undefine it
again).
