the CBC clean and invalidate is done for gk20a for bug 1409151, now
it's time to do the same fo gm20b. the text of this change is
strictly copied from gk20a, simply to make build pass.

gk20a_ltc_init_comptags and gk20a_ltc_clear_comptags are defined
in ltc_gk20a.c, gm20b has its own init/clear functions, so remove
these two from ltc_common.c
change nvhost_allocator_init to gk20a_allocator_init, this is a
left-over after rebase, just like the above 2 function definitions,
so fix it.

This patch adds an interface for the gk20a driver to have
generic ops which are implemented by a chip specific HAL
layer. The HAL layer is provided by the gpu_ops struct which
defines function pointers for chip specific oeprations. This
is necessary for supporting multiple chips with the same
code base and minimal per chip hacking.
Also, since much code is common except in the HW headers
that are needed, the LTC common code is compiled by first
including the necessary chip specific header(s) and then
including the ltc common code file.
This allows for easy updating of functions that are only
different between chips as a result of register offset and
field changes whereas the HAL provides the mechanism for
functions that have actual semantic changes.

This far the scaling has been disabled only when we suspend the
system and therefore we unnecessarily keep gpu workers running even
if the gpu itself would be railgated. This is not proper behaviour
and it causes a race in suspend sequence.
This patch reorders scaling disable to happen always when we turn off
the GPU.

Lbreq interrupt can assert when there is memory back pressure. Do not
enable it as either stalling or nonstalling interrupt.

TLB invalidate can have a race if several contexts use the same
address space. One thread starting an invalidate allows another
thread to submit before invalidate is completed.

This change disables gr engine before calling into pmu
for saving zbc and re-enables once it is finished.
Looks like NV_PPWR_PMU_BAR0_FECS_ERROR_CODE_PRI_TIMEOUT
error during access of NV_PLTCG_LTCS_LTSS_DSTG_ZBC_COLOR_CLEAR_VALUE
happens because of active concurrent memory traffic.

gk20a_channel_busy is called to host gpu so that gk20a can be accessed.
But it may return error like if gpu fails to be powered on. Always check
the return value of gk20a_channel_busy to avoid illegal access to gk20a.

Set syncpt_aggressive_destroy = true and enable gpu channels'
syncpt free at channel_unbind() time.
This is more agrressive level to free a syncpt.

Add infrastructure to allow freeing gpu channels' syncpts at
channel_unbind()
Currently, we free the syncpt at channel_free() only.
But we can free the syncpt when channel becomes idle.
When we do channel_unbind(), channel cannot be scheduled and
hence we can destroy its syncpt.
Channel will request again for new syncpt when it has new work
to do.
This feature will be enabled with boolean flag
syncpt_aggressive_destroy

Currently gk20a_channel_idle() drops pm_runtime references to gk20a
and then drops platform dependencies. As we usually delay powering down
gk20a, we may end up to case where the platform dependencies are
turned off at the moment we start powering down gk20a. Power off
sequence may use platform dependencies for informing completion of
the last work, wait-for-idle, and therefore we may simply drop the
information about job completion.
This patch adds missing calls to power up platform dependencies for
the time we submit the last work.
