This patch series implements the mask for unimplemented priority bits in
arm-gic. Which will return the expected number of priority bits on read.

Changes for V2:
    Followed gicv3 code for defining mask for unimplemented bits
    Hardcoded num priority bits for A9 and ARM11MPCore boards
Changes for V3:
    Fixed the code as suggested in V1.
    Implemented checks for max and min priority bits.

Sai Pavan Boddu (3):
  arm_gic: Mask the un-supported priority bits
  cpu/a9mpcore: Set number of GIC priority bits to 5
  cpu/arm11mpcore: Set number of GIC priority bits to 4

Applied to target-arm.next, thanks. (I tweaked a few of
the commit messages to give a little more detail.)
