Allow users to specify "big page" mode when allocating GPU
memory. This will attempt to allocate contigious units of 64k
bytes per instead of the usual PAGE_SIZE units. If the allocation
fails, then automatically fall back to allocate the rest of the
region with 4K pages. This means that potentially any allocation
could be comprised of a mixture of 64k chunks and 4k chunks.

Userspace passes a set of values indicating how it
uses each buffer it allocates, which were previously
ignored. These are useful hints for debugging and
profiling applications. These flags will be exposed
through ftrace and debugfs in later patches.

The Android sync point framework will replace the synchronization
previously implemented by genlock. This change implements the KGSL
component of the sync point framework by creating a fence that is
automatically signaled by KGSL when it's timestamp expires. The
fence FD is returned to the user driver so that another process
can wait for the sync point.

The pdata structure and associated structs have no business being
in msm_kgsl.h. Move them to include/mach/kgsl.h where they can
thrive in a non-userspace facing environment.
