gpu: nvgpu: Add a new device manager unit
...
This adds a new device management unit in the common code responsible
for facilitating the parsing of the GPU top device list and providing
that info to other units in nvgpu.
The basic idea is to read this list once from HW and store it in a
set of lists corresponding to each device type (graphics, LCE, etc).
Many of the HALs in top can be deleted and instead implemented using
common code parsing the SW representation.
Every time the driver queries the device list it does so using a
device type and instance ID. This is common code. The HAL is responsible
for populating the device list in such a way that the driver can
query it in a chip agnostic manner.
Also delete some of the unit tests for functions that no longer
exist. This code will require new unit tests in time; those should be
quite simple to write once unit testing is needed.

gpu: nvgpu: modify gmmu page table entry functions
...
Move below chip agnostic gmmu pte functions to common/mm/gmmu/pte.c.
- gmmu_aperture_mask()
- pte_dbg_print()
Default big page size for all chips is 64K. So, move
gp10b_mm_get_default_big_page_size() to common file and rename as
nvgpu_gmmu_default_big_page_size().
Modify gv11b_gpu_phys_addr() to use get_iommu_bit() hal.

gpu: nvgpu: igpu and dgpu driver libs
...
Different build flags are used for iGPU and dGPU in
safety build. In order to support dGPU in unit tests,
a separate library is needed for the driver.
Added makefiles to build:
- libnvgpu-drv-igpu.so
- libnvgpu-drv-dpgu.so
Updated scripts and units makefiles to use libnvgpu-drv-igu
by default.
