Added all registers added to gk20a and gm20b to gp10b. Remove gp10b
trim registers, because they will not be accessed by CPU.

We use &ch->error_notifier_mutex to protect
writes and free of error notifier
But we currently do not protect reading of
notifier in gk20a_fifo_set_ctx_mmu_error()
and vgpu_fifo_set_ctx_mmu_error()
Add new API gk20a_set_error_notifier_locked()
which is same as gk20a_set_error_notifier()
but without the locks.
In *_fifo_set_ctx_mmu_error() APIs, acquire
the mutex explicitly, and then use this new
API
gk20a_set_error_notifier() will now just call
gk20a_set_error_notifier_locked() within
a mutex

Store pending sema waits so that they can be explicitly handled when
the driver dies. If the sema_wait is freed before the pending wait is
either handled or canceled problems occur.
Internally the sync_fence_wait_async() function uses the kernel timers.
That uses a linked list of possible events. That means every so often
the kernel iterates through this list. If the list node that is in the
sync_fence_waiter struct is freed before it can be removed from the
pending timers list then the kernel timers list can be corrupted. When
the kernel then iterates through this list crashes and other related
problems can happen.

Check if the GPU is present after each register read. If the a register
read returns 0xffffffff then it's possible the GPU has fallen off the
bus for some reason or another. However, to confirm that a register read
is due to a dead GPU vs just a 0xffffffff being returned by happenstance
the chip ID register is read which should never return 0xffffffff. If
that read returns 0xffffffff as well then certainly the GPU is dead.

Allow SW to force a semaphore release. Typically SW waits for a
semaphore to reach the value right before the semaphore release
value before doing a release. For example, assuming a semaphore
is to be released by SW by writing a 10 into the semaphore, the
code waits for the semaphore to get to 9 before writing 10.
The problem with this happens when trying to shutdown the GPU
unexpectedly. When aborting a channel after the GPU has terminated
the GPU is potantially no longer processing anything. If a SW
semaphore release is waiting on the semaphore to reach N-1 before
writing N to the semaphore N-1 may never get written by the GPU.
This obviously causes a hang in the SW shutdown. The solution is
to let SW force a semaphore release in the channel_abort case.

Add a private tsg struct for the TSG file descriptors. This allows

The private_data field in the file pointer passed to release() for
channels originally pointed directly to the referenced channel. The
problem with this is that when the driver is killed and the channel
mmeory is freed that pointer becomes invalid.
The necessity of that channel is to get access to the gk20a struct that
owns the channel. This can instead be accomplished by making a new
private data struct that has a pointer to the gk20a struct directly
instead of requiring the channel to be valid. This lets the release()
function work even if the channels are gone (though in such cases the
release function doesn't do very much).

In gk20a_scale_target(), to check for duplicate
freq requests we compare current frequency with
devfreq->previous_freq
But for very first request after boot, we have
devfreq->previous_freq set to MIN freq
And in case we evaluate new frew as MIN freq
then we skip calling postscale() and scaling
of EMC clock
This results in keeping EMC at MAX value
To fix this, add new variable last_freq in
gk20a structure.
Use this variable to store frequency value
and to compare for duplicate requests
