hwc/copybit: Add Color layer support in MDP Copybit composition.

1. Color layer has a destination rectangle, RGBA color and plane
   alpha. There is no gralloc buffer. Layer flag HWC_COLOR_FILL
   denotes color layer. MDP BLIT happens via MDP_SOLID_FILL mode.
2. There is no color member in HWC layer, so RGBA color value is
   passed via "tranform" member from framework to HAL.
3. Update HWC query to enable framework to query for Color layer
   support in HAL, at run-time.

Use msm8974 directory for msm8226

- The code in msm8x26 directory is oudated and 8974 works
  with no issues.
- Remove unneeded msm8x26 directory
- Add symlink from msm8226 to msm8974 so current macros that
  use display/$(TARGET_BOARD_PLATFORM) to find needed headers
  continue to work as expected.

display: Add support for MDP 4.1

 * MDP 4.1 does not support the borderfill pipe and the baselayer logic
   should not be used.
 * Only use 3 pipes for MDP 4.1.
