Allow compatibility with ICS EGL for OMX

The new headers define the qcom video buffer format
(HAL_PIXEL_FORMAT_YCbCr_420_SP_TILED) as 0x7FA30C03, ICS used 0x108.

Trying to play a video with the ICS Adreno driver results in
it rejecting the buffers because 2141391875 (0x7FA30C03) is an
unknown buffer format, so use the QCOM_ICS_COMPAT CFLAG to
fallback to the older enum.

Do NOT use this with JB Adreno blobs.
