The alloc_insty_block() function in the MM HAL is not a HAL. It does
not abstract any HW accesses; instead it just wraps a dma allocation.
As such remove it from the HAL and move the single gk20a implementation

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
The nvgpu_worker_ops containg the following function pointers
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.
