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.

Remove a block of code that dumped the ringbuffer contents after they
were extracted. The dump is no longer needed and the longer we
stick around dumping things to the console with the mutexes locked,
the better the chance that the watchdog will come bite us.

Don't BUG() if we can't find a valid context to recover to; just fail and
go into a zombie state. This usually happens after a first hang goes bad
and the system keeps hanging while trying to find its way. The problem with
a BUG() in this case is that the system goes down and we can't recover the
snapshot or other debug information.

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.

Clean up kgsl_pwrctrl_sleep() and kgsl_pwrctrl_wake() to make
state transistions clearer. Add kgsl_pwrctrl_request_state()
and kgsl_pwrctrl_set_state() to make it easier to debug the
state machine.

This GPU has a larger instruction store, so more memory
needs to be reserved for saving shader state when context
switching.
The initial vertex and pixel partitioning of the
instruction store also needs to be different.

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.

We are starting to accumulate a lot GPU specific information,
and it is handy to keep it all in one place where new core IDs,
firmware and device functions can be easily added.

The A3XX code likes to use CP_ as a prefix for ringbuffer
commands rather then the legacy PM4 prefix. Since it is more
correct, switch the A2XX code over now to make it easier to
integrate A3XX into the mix.

Move some of the drawctxt functions that are common
to A2XX and A3XX back to the generic drawctxt code
and headers.
