Add new ioctls for per context timestamps.
Timestamp functions (read/write/wait) will now be context
specific rather than only using the global timestamp.
Per context timestamps is a requirement for priority
based queueing.

The code for IOCTL_KGSL_DEVICE_REGREAD was removed long ago
but the header was never cleaned up.

APQ8064 has two AXI ports attached to the GPU with an IOMMU on both.
The VBIF can be programmed to use a round-robin arbitration to access
the ports equally, so we need to program both IOMMUs with the same
pagetable to make sure that the GPU can get where it needs to go.
All this involves a board file infrastructure change that affects 8960
too, but no functional changes are happening for that platform.

Idle the core before changing the gpu clock as instability
is caused on some platforms on changing the clock freq when
core is busy.

Userspace will set a flag in the context if preambles are in use. If
they are, we can safely skip save and restore commands for the
context. GMEM save/restore is still required. To improve performance,
preamble commands are skipped when the context hasn't changed since
the last issueibcmds.

Introduce an enum for the max memory type supported by kgsl. This is
used by kgsl_test to pass the correct parameters to kgsl.

Still allow the clocks a per-platform map for clock error checking,
but use a const array of their identical names.

Add support for triggering asynchronous events when a timestamp
expires. The infrastructure is generic enough to support different
sorts of events and callbacks. The first user of the event
infrastructure is a way to release a genlock locks on behalf of a
user space process.

kgsl now supports the use of 2 types of MMU. One is
the GPU's internal MMU and the other is IOMMU. Both
MMU cannot be active at the same time. The MMU type
can be selected at compile time via config option.
A boot command line parameter can be used to override
the type of MMU selected at compile time.
