ebd5833327 Blackfin: fix incomplete renaming of the bfin-twi-lcd driver
The sed used to rename the bfin-twi-lcd only replaced the first instance
rather than all which led to the resources not being enabled when the
driver was built as a module.

fa48f84a8c Blackfin: unify memory map headers
Many aspects of the Blackfin memory map is exactly the same across all
variants.  Rather than copy and paste all of these duplicated values in
each header, unify all of these into the common Blackfin memory map header
file.  In the process, push down BF561 SMP specific stuff to the BF561
specific header to keep the noise down.

This is because the #ifdef's in bfin_serial_5xx.h are messed up. More
specifically, they add/remove the uart_{rts,cts}_pin fields in
bfin_serial_resources based on whether the particular port has rts/cts enabled,
as opposed to when either port has it enabled.

This patch fixed this.
