b6ed2c6d96 gpu: nvgpu: Fix build with Tegra DVFS disabled 
Avoid using Tegra DVFS APIs when it is not built in. This is done by
protecting the code using Tegra DVFS with #ifdef.

7a4cb4a6ab gpu: nvgpu: gv11b: gfxp wfi timeout 
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

25440e63d2 gpu: nvgpu: move platform_gk20a.h to linux 
Move gk20a/platform_gk20a.h to linux specific directory as
common/linux/platform_gk20a.h since this file includes all linux specific
stuff

Fix #includes in all the files to include this file with correct path

Remove #include of this file where it is no more needed

Fix gk20a_init_sim_support() to receive struct gk20a as parameter
instead of receiving linux specific struct platform_device

00e52529a8 gpu: gp10b: add gfxp_wfi_timeout sysfs node 
Add a sysfs node to allow root user to set PRI_FE_GFXP_WFI_TIMEOUT, for gp10b
only, in units of sysclk cycles. Store the set value in a variable, and write
the set value to register after GPU is un-railgated.

NV_PGRAPH_PRI_FE_GFXP_WFI_TIMEOUT is engine_reset after Bug 1623341.

Change default value to be specified in cycles, rather than time.  This value
is almost the current value in cycles calculated each boot.
