gpu: nvgpu: unify nvgpu and pci probe

Browse Source 
We have completely different versions of probe for
nvgpu and pci device
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()
This also helps to bringup all debug nodes to pci device

Pass debugfs_symlink name as a parameter to gk20a_debug_init()
This allows us to set separate debugfs symlink for nvgpu
and pci device

In case of railgating, cde and ce debugfs, check if
platform supports them or not

Copy vidmem_is_vidmem from platform to mm structure
and set it to true for pci device

Return from gk20a_scale_init() if we don't have either of
governor or qos_notifier

Fix gk20a_alloc_debugfs_init() and gk20a_secure_page_alloc()
to receive device pointer instead of platform_device

Export gk20a_railgating_debugfs_init() so that we can call
it from gk20a_debug_init()
