On gv11b we can have multiple SMs per TPC. Add sm_per_tpc in
vgpu constants to properly dimension the virtual SM to TPC/GPC
mapping in virtualization case.
Use TEGRA_VGPU_CMD_GET_SMS_MAPPING to query current mapping.

Add an alignment check for compressible-kind fixed-address
mappings. If we're using page size smaller than the comptag line
coverage window, the GPU VA and the physical buffer offset must be
aligned in respect to that window.

For gv11b, configured gfx preemption wfi timeout in usec.
Set timeout unit as usec in gr_gv11b_init_preemption_state.
Used default timeout as 1msec and this timeout value can
be modified through sysfs node:
/sys/devices/gpu.0/gfxp_wfi_timeout_count
For gp10b:
gfxp_wfi_timeout_count is in syclk cycles
For gv11b:
gfxp_wfi_timeout_count is in usec

-New fuse ops is added to set NVGPU_SEC_PRIVSECURITY
and NVGPU_SEC_SECUREGPCCS bits in g->enabled_flags
during hal initialization
-For igpu non simulation platforms, fuses are read
to decide if gpu should be allowed to boot or not.
--Do not boot gpu if priv_sec_en is set but wpr_enabled
is not set to 1 or vpr_auto_fetch_disable is not set to 0
--With priv_sec_en set, all falcons have to boot
in LS mode and this needs wpr_enabled set to 1
AND vpr_auto_fetch_disable set to 0. In this case
gmmu tries to pull wpr and vpr settings from tegra mc

Add a translation layer to convert from the NVGPU_AS_* flags to
to new set of NVGPU_VM_MAP_* and NVGPU_VM_AREA_ALLOC_* flags.
This allows the common MM code to not depend on the UAPI header
defined for Linux.
In addition to this change a couple of other small changes were
made:
1. Deprecate, print a warning, and ignore usage of the
NVGPU_AS_MAP_BUFFER_FLAGS_MAPPABLE_COMPBITS flag.
2. Move the t19x IO coherence flag from the t19x UAPI header
to the regular UAPI header.

Most of VGPU code is linux specific but lies in common code
So until VGPU code is properly abstracted and made os-independent,
move all of VGPU code to linux specific directory
Handle corresponding Makefile changes
Update all #includes to reflect new paths
Add GPL license to newly added linux files
