Add support for IP registering mechanism for runtime
callback and perfmux read/writes.
void tegra_soc_hwpm_ip_register(struct tegra_soc_hwpm_ip_ops *hwpm_ip_ops);
IP's callback are called to disable and enable IP runtime pm.
At this moment, only VIC/NVENC/OFA driver registration is supported.
Also will take-up perfmux register read/write in follow-up patch.

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 floorsweep_info IOCTL for userspace to query IP instance information
This IOCTL will update the floorsweep_info struct with
- status: valid - query ip_type is valid but IP instances are absent
invalid - query ip_type is invalid
exists - query ip_type is valid and IP instances are available
- ip_inst_info: 64-bit mask, where each set bit corresponds to available
IP instance.
All reserving resources depending on IP floorsweep info.

- As regops ioctl status is an output from kernel, the status cannot be
invalid. So, remove TEGRA_SOC_HWPM_REG_OP_STATUS_INVALID define.
- Redefine regops ioctl status to make SUCCESS equivalent to value 0.
- Add TEGRA_SOC_HWPM_REG_OP_STATUS_WR_FAILED to indicate failure in
regops write command.

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
