This unit test covers the page_table map/unmap logic as well
as low level PDE/PTE handling.
This patch contains a first phase aiming to cover most
functionality and code coverage but it does not cover
most error handling cases nor formal requirements.

Add a unit test to cover the pd_cache unit. This unit is
responsible for maintaining the page directory allocations.
It's effectively a DMA slab allocator since we want to be
able to pack multiple sub page sized page directories into
a single page.

This unit test covers the nvgpu allocator high level logic for
calling nvgpu allocator imlementation routines. The nvgpu_allocator
code is generally very simple.
This gets to >90% coverage of the module. Once the fault injection
code is merged the failure path after nvgpu_mutex_init() will also
be coverable.
