Add ioctl support to configure and read the max number of lines/ways
in a L2 cache set that can be marked as EVICT_LAST. This is accomplished
through two new ltc hals: set_l2_max_ways_evict_last,
get_l2_max_ways_evict_last. These hals will only be set for nvgpu-next
chips. Incase of legacy chips, the IOCTLs will return error -ENOSYS.

Generate following litter constants to get the number of sets in a l2
slice and the number of ways in each set:
- GPU_LIT_NUM_LTC_LTS_SETS
- GPU_LIT_NUM_LTC_LTS_WAYS

Add gpu characteritics flag: NVGPU_L2_MAX_WAYS_EVICT_LAST_ENABLED to
allow userspace driver to determine if L2_MAX_WAYS_EVICT_LAST ioctl is
supported.

42033ac29e gpu: nvgpu: Simplify include path for building as an external module 
When building NVGPU, it is necessary to define 'srctree.nvgpu' so that
the NVGPU driver knows where to find its include files. When building as
an in-tree module, the overlay infrastructure defines this and when
building as an out-of-tree module, it is necessary to define this in the
Makefile that is building NVGPU. Given that the NVGPU header are located
in the NVGPU source tree, it is not necessary and simpler if the NVGPU
Makefile defines 'srctree.nvgpu' path if it is not already specified.

Furthermore, when building NVGPU as an external module with support for
the upstream host1x driver enabled, the necessary host1x header file
that is required for building NVGPU is being copied into the build
directory for NVGPU. Rather than copying the header file, it is
preferred that the path for locating the header file is passed to the
NVGPU Makefile. Add support for doing this by adding 'srctree.host1x'
variable that indicates where the host1x header files can be found
when support for the upstream host1x driver is enabled.

09fb445878 gpu: nvgpu: remove ipa to pa conversion WAR 
WAR assume 1:1 IPA to PA mapping when hyp_read_ipa_pa_info fails for
the syncpt address which falls into syncpt shim aperture. API
nvgpu_mem_phys_sgl_ipa_to_pa() is taking care of IPA to PA mapping for
the syncpts which makes this WAR invalid.

Patch removes the WAR.
