msm: iommu: Split rotator/mdp iommu domains
Finer granularity is needed when mapping into the IOMMU's for
rotator and mdp for secure playback. During secure playback
HLOS will only have access to map into one context bank. The
other context bank is secured and programmed by TrustZone.
Divide DISPLAY_DOMAIN into DISPLAY_WRITE_DOMAIN and
DISPLAY_READ_DOMAIN. Divide ROTATOR_DOMAIN into ROTATOR_SRC_DOMAIN
and ROTATOR_DST_DOMAIN.
