1. Add support for UBWC allocation in the Gralloc APIs for aligned width, aligned height and buffer size. A client can request for UBWC allocation by sending UBWC specific HAL pixel format or by setting GRALLOC_USAGE_PRIVATE_ALLOC_UBWC flag in the usage flags. 2. Gralloc allocates UBWC aligned buffer, only if format is supported by GPU and MDP and no CPU usage flags are set. Otherwise it allocates linear buffer. 3. If UBWC conditions are met, gralloc sets PRIV_FLAGS_UBWC_ALIGNED in private handle flags to tell client that allocated buffer has UBWC alignment. This flag remains unset by default. 4. Add helper functions in gralloc to calculate UBWC meta buffer size for RGB* formats. 5. Add UBWC HAL pixel format HAL_PIXEL_FORMAT_YCbCr_420_SP_VENUS_UBWC which has been defined by Video module. 6. Add AdrenoMemInfo api to query, if GPU supports UBWC for a format. 7.MDP driver expects UBWC specific pixel format defined by MDP header. Change-Id: I5b4344bc90aa498dbdb7bb8100e70ed7728e6ea5
