The vm object num_user_mapped_buffers was declared as an int. However,
it is an unsigned value. Being a signed value required a cast to
unsigned when calling nvgpu_big_zalloc() which causes a CERT-C INT31
violation. So, avoid the cast and use an unsigned type. And fix related
INT30 violations related to num_user_mapped_buffers as well.
To avoid introducing new MISRA/CERT-C violations, update the upstream
user of these changes, fifo/channel.c and make the equivalent uses of
this value, num_mapped_buffers a u32 as well.

Currently, both clk_arb and channels use their own implementation of
a background worker. These implementations are almost identical and can
be extracted out into a single self-contained unit name nvgpu_worker.
Another advantage of using a single worker unit is to avoid duplication
of Unit Tests for this unit in other units.
channel and clk_arb units provide their own specific implementations
via an ops interface named nvgpu_worker_ops which is a part of the
nvgpu_worker struct.
The following high level APIs are exposed by the nvgpu_worker
nvgpu_worker_should_stop
nvgpu_worker_enqueue
nvgpu_worker_init
nvgpu_worker_deinit

pre_process
wakeup_early_exit
wakeup_post_process
wakeup_process_item
wakeup_condition
wakeup_timeout
The specific code in channel and clk_arb is changed to use the above
implementations instead of their own separate implementations.

Add a new MM HAL directory to contain all MM related HAL units.
As part of this change add cache unit to the MM HAL. This contains
several related fixes:
1. Move the cache code in gk20a/mm_gk20a.c and gv11b/mm_gv11b.c to
the new cache HAL. Update makefiles and header includes to take
this into account. Also rename gk20a_{read,write}l() to their
nvgpu_ variants.
2. Update the MM gops: move the cache related functions to the new
cache HAL and update all calls to this HAL to reflect the new
name.
3. Update some direct calls to gk20a MM cache ops to pass through
the HAL instead.
4. Update the unit tests for various MM related things to use the
new MM HAL locations.
This change accomplishes two architecture design goals. Firstly it
removes a multiple HW include from mm_gk20a.c (the flush HW header).
Secondly it moves code from the gk20a/ and gv11b/ directories into
more proper locations under hal/.
