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.
Bug 1932782
