msm: kgsl: Add a flag to mark user mapped GPU buffers

Add a flag in /sys/kernel/debug/kgsl/kgsl-3do/proc/<pid>/mem
file to indicate for each GPU buffer if it is mapped to userspace
in <pid> or not.

msm: mdss: disable MDP hw underflow recovery

When MDP underflows, hardware will automatically try to issue a reset to
recover from it. Potential issue has been identified when reset happens
on two video interfaces at the same time which may lead to a hw lockup.
To avoid such situations disable the hardware underflow recovery, MDP
will still automatically recover at the beginning of next frame.

cma: Add support for memory limits

Currently, when dynamically placing regions CMA will allow the memory
to be placed anywhere, including highmem. Due to system restrictions,
regions may need to be placed in a smaller range. Add support to
devicetree to allow these regions to have an upper bound on where they
will be placed.

cma: Allow option to use strict memblock_reserved memory

Despite all the performance optimizations, some clients are
still unable to use CMA because of the allocation latency.
Rather than make those clients use a separate set of APIs,
extend the CMA code to allow clients to keep the memory out of
the buddy allocator. Since the pages never actually go to the
buddy allocator, allocation and freeing is only based on the bitmap
allocator to find the appropriate region.

arm: Add option to skip buffer zeroing

The DMA framework currently zeros all buffers because it (righfully so)
assumes that drivers will soon need to pass the memory to a device.
Some devices/use case may not require zeroed memory and there can
be an increase in performance if we skip the zeroing. Add a DMA_ATTR
to allow skipping of DMA zeroing.
