Suppress error message when nvgpu tries to load VBIOS overlay, but
one is not found. This situation is normal. This is done by moving
gk20a_request_firmware() to be nvgpu generic function
nvgpu_request_firmware(), and adding a NO_WARN flag to it.
Introduce also a NO_SOC flag to suppress attempt to load firmware
from SoC specific directory in addition to the chip specific
directory. Use it for dGPU firmware files.

Extract out common steps into nvgpu_probe() function
and separate it out in new file nvgpu_common.c
Divide task of nvgpu_probe() into further smaller
functions
Do platform specific things (like irq handling,
memresource management, power management) only in
individual probes and then call nvgpu_probe() to
complete the common initialization
Move all debugfs initialization to common gk20a_debug_init()

Pass debugfs_symlink name as a parameter to gk20a_debug_init()

We currenlty initialize both runtime PM and pm_domains frameworks
and use pm_domain to control runtime power management of NvGPU
But since GPU has a separate rail, using pm_domain is not
strictly required
Hence remove pm_domain support and use runtime PM only for all
the power management
This also simplifies the code a lot
Initialization in gk20a_pm_init()
- if railgate_delay is set, set autosuspend delay of runtime PM
- try enabling runtime PM
- if runtime PM is now enabled, keep GPU railgated
- if runtime PM is not enabled, keep GPU unrailgated
- if can_railgate = false, disable runtime PM and keep
GPU unrailgated
Set gk20a_pm_ops with below callbacks for runtime PM
static const struct dev_pm_ops gk20a_pm_ops = {
.runtime_resume = gk20a_pm_runtime_resume,
.runtime_suspend = gk20a_pm_runtime_suspend,
.resume = gk20a_pm_resume,
.suspend = gk20a_pm_suspend,
}
Move gk20a_busy() to use runtime checks of pm_runtime_enabled()
instead of using compile time checks on CONFIG_PM
Clean up some pm_domain related code
Remove use of gk20a_pm_enable/disable_clk() since this
should be already done in platform specific unrailgate()/
railgate() APIs
Fix "railgate_delay" and "railgate_enable" sysfs to use
runtime PM calls
For VGPU, disable runtime PM during vgpu_pm_init()
With this, we will initialize vgpu with vgpu_pm_finalize_poweron()
upon first call to gk20a_busy()
