Girish Pathak 268aad6744 ArmPlatformPkg: PCD to swap red/blue format for HDLCD
This change adds a new PCD PcdArmHdlcdSwapBlueRedSelect
to swap values for HDLCD RED_SELECT and BLUE_SELECT registers
on platforms where blue and red hardware lines are swapped.

If set to TRUE in the platform dsc, HDLCD library will swap the values
while setting RED_SELECT and BLUE_SELECT registers. The default
value of the PCD is FALSE.

NOTE: The motive for this is that a discrepancy in the Red/Blue lines
exists between some VersatileExpress platforms.  Rather than have
divergent code, this build switch allows a simple, pragmatic solution.
