Adds generic PM domain support for Tegra SoCs but this series only
enables support for it on Tegra 64-bit devices. There is no reason why
this cannot be enable for Tegra 32-bit devices, but to keep the patch
series to a minimum only 64-bit devices are enabled so far.

This series has been boot tested on Tegra210 as well as various 32-bit
Tegra platforms.

Summary of changes since V5 [2]:
- Split series into 2 series, separating PMC fixes [3] from genpd changes
- This series is based upon fixes series (which is now in -next)
- Added patch to fix removal of genpd subdomain
- Added patch to get last genpd that was added
- Fixed locking in function to remove genpd
- Updated Tegra PMC driver to ensure power-domains cannot be controlled
  by both legacy Tegra APIs and generic PM domain framework
- Removed powergate list from Tegra PMC driver and updated removal of
  power domains to use new genpd APIs.

Summary of changes since V4 [1]:
- Re-worked fix to handle base address on probe failure
- Added patch to lock around simultaneuous accesses to PMC registers
- Added patch to change powergate and rail IDs to unsigned type
- Added patch to fix testing of powergate state
- Updated patch to check for valid powergates to use a bitmap
- Updated Tegra DT PMC bindings per Rob H's feedback
- Updated Tegra power domains binding per Thierry's feedback
- Updated Tegra generic power domain support per Thierry's feedback

Summary of changes since V3 [0]:
- Dropped tegra124 support for now
- Removed MC flush support per feedback from Thierry
- Cleaned up the PMC changes per feedback from Thierry
- Added support for tegra210
