IP perfmon base address value is determined by iomap(). This iomap
address is dependent on many factors like platform, carveout, etc.
Currently, soc hwpm user passes static perfmon addresses to execute
reg ops.
Modify hwpm_resource_aperture struct to hold absolute/static start and
end address of the aperture. These new variables will indicate absolute
register range of the aperture.
Modify reg ops ioctl to determine aperture of given phys addr based on
IP's absolute register range.

Add a driver for programming the Tegra SOC HWPM path. SOC HWPM allows
performance monitoring of various Tegra IPs.
The profiling tests cases are configured through IOCTLs sent by a
userspace profiling app. The IOCTLs provide the following features:
- IP discovery and reservation
- Buffer management
- Whitelist query
- Register read/write ops
