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

All the linux specific error_notifier codes are defined in linux specific
header file <uapi/linux/nvgpu.h> and used in all the common driver
But since they are defined in linux specific file, we need to move all the
uses of those error_notifiers in linux specific code only
Hence define new error_notifiers in include/nvgpu/error_notifier.h and
use them in the common code
Add new API nvgpu_error_notifier_to_channel_notifier() to convert common
error_notifier of the form NVGPU_ERR_NOTIFIER_* to linux specific error
notifier of the form NVGPU_CHANNEL_*
Any future additions to error notifiers requires update to both the form
of error notifiers
Move all error notifier related metadata from channel_gk20a (common code)
to linux specific structure nvgpu_channel_linux
Update all accesses to this data from new structure instead of channel_gk20a
Move and rename below APIs to linux specific file and declare them
in error_notifier.h
nvgpu_set_error_notifier_locked()
nvgpu_set_error_notifier()
nvgpu_is_error_notifier_set()
Add below new API and use it in fifo_vgpu.c
nvgpu_set_error_notifier_if_empty()
Include <nvgpu/error_notifier.h> wherever new error_notifier codes are used

This patch removes the dependency on the header file "uapi/linux/nvgpu.h"
for regops_gk20a.c. The original structure and definitions in the
uapi/linux/nvgpu.h is maintained for userspace libnvrm_gpu.h. The
following changes are made in this patch.
1) Defined common versions of the NVGPU_DBG_GPU_REG_OP* definitions inside
regops_gk20a.h.
2) Defined common version of struct nvgpu_dbg_gpu_reg_op inside
regops_gk20a.h naming it struct nvgpu_dbg_reg_op.
3) Constructed APIs to convert the NVGPU_DBG_GPU_REG_OP* definitions from
linux versions to common and vice versa.
4) Constructed APIs to convert from struct nvgpu_dbg_gpu_reg_op to
struct nvgpu_dbg_reg_op and vice versa.
5) The ioctl handler nvgpu_ioctl_channel_reg_ops first copies from
userspace into a local storage based on struct nvgpu_dbg_gpu_reg_op which
is copied into the struct nvgpu_dbg_reg_op using the APIs above and
after executing the regops handler passes the data back into userspace
by copying back data from struct nvgpu_dbg_reg_op to struct
nvgpu_dbg_gpu_reg_opi.

-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
