Video: ARM CLCD: Better fix for swapped IENB and CNTL registers
On PL111, as found on Realview and other platforms, these registers are
always arranged as CNTL then IENB. On PL110, these registers are IENB
then CNTL, except on Versatile platforms.
Re-arrange the handling of these register swaps so that PL111 always
gets it right without resorting to ifdefs, leaving the only case needing
special handling being PL110 on Versatile.
Fill out amba/clcd.h with the PL110/PL111 register definition
differences in case someone tries to use the PL110 specific definitions
on PL111.
