msm_fb: display: Add pre-multiplied alpha support for MDP4.

MDP4 blend logic differs from GPU blend implementation as MDP4
does not differentiate between pre-multiplied alpha layers and
non pre-multiplied alpha layers. Check layers for pre-multiplied
alpha and change blend logic accordingly.

Iommu buffers from overlay destinated for WFD (mixer2) are
not freed after kickoff. This patch will free those iommu
buffers.

msm_fb: display: Fix blend configuration for MDP4.1

MDP4.1 blend operation registers are not double buffered and
take effect as soon as they are configured. Configuring these
registers at any place other than between dma and vsync produce
flickers as new blend values would get applied to previous
mixer configurations. Configure blend operation registers just
after dma is over, before vsync.

msm: kgsl: Increase the virtual GPU range for the IOMMU

Instead of a fixed 256MB virtual range for both the GPUMMU and IOMMU, make
the virtual range a property of the MMU engine and set the IOMMU range to
2GB.  Technically we could go all the way up to 4G, but even 2G is far out
of the realm of possiblity in the current generation, and we wanted to
reserve some of the space for future enhancements.

msm: kgsl: Do bounds checking on user supplied GPU addresses

Add bounds checking to kgsl_sharedmem_find_region to ensure that GPU
addresses supplied by the user via KGSL_IOCTL_SHAREMEM_FREE and
KGSL_IOCTL_CFF_SYNCMEM are within a valid range for the MMU scheme of
choice.
