Kumar Gala 016bcb3b81 drm/msm: drop ARCH_MSM Kconfig depend
The ARCH_MSM depend is redundant with ARCH_MSM8960, so we can remove it.
Additionally, we are splitting Qualcomm MSM support into legacy (ARCH_MSM)
and multiplatform (ARCH_QCOM).  The MSM8960 with be ARCH_QCOM going forward
so dropping ARCH_MSM will work properly for the new ARCH_QCOM multiplatform
build.

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
