Simplify the MC-HWPM driver and fix the hang seen during probe of it.
These changes are made to scale the driver for future SOCs as well.
The hang is seen because MC registers are accessed in function
get_platform_dram_num_channels() before the MC aperture is io-mapped.

Make mc-hwpm module oot. Below are the reasons why
making a fresh copy in nvdia-oot folder -
- hwpm is introduced from T234 onwards
- mc-hwpm is dependent on mc driver. nvidia-oot
uses upstream mc driver. Hence mc-hwpm should also
use upstream mc driver.
- Thats why porting changes needed in mc-hwpm driver
to be incompatible with upstream mc driver
