Modify OS agnostic files in common, hal and include folder to use MIT
license. This will allow the files to be shared between different OSes.
Modify OS specific files in os/linux and uapi folders to add SPDX

Below listed functions are defined and used in the same source file,
hence update the functions to be static.
- tegra_hwpm_element_disable
- tegra_hwpm_element_reserve
- tegra_hwpm_element_release

- Make clock reset functions into HALs. This way we can control
clock-reset logic for any chip. Set clock-reset HAL pointers to
appropriate functions.
- Remove clock-reset function wrappers as these will not be required and
corresponding HAL pointers will be used.
- As clock reset init is defined as a HAL, modify probe logic to
initialize chip info before invoking any HALs.
- Move common/primary HAL validation logic to common code and implement
new HAL to validate chip specific HALs. This way we can ensure that HAL
pointers are set as expected.
- Keep only one definition for t234_hwpm_init_chip_info as t234 should
always be initialized and hence only single definition should be
available.
- Expected return value of 0 indicates success and any other value
(mostly negative in current logic) indicates error, compare function
returns with 0 to print error in tegra_hwpm_release().
- Since a build can support both ACPI and device tree, update
init_chip_info() to retrieve chip information from ACPI and device tree
in case of failure.

- Zeroing of PMA trigger registers is unnecessary. Remove corresponding
logic from HWPM teardown function.
- During device open, add a check for PMA/RTR status. This will ensure
that PMA/RTR are ready to start new profiling session. Device open will
fail if RTR and PMA enginestatus is not ready(idle).
- SOC HWPM driver disables and releases all reserved IPs before teardown
steps. Update teardown logic to zero out IP allowlist registers during
teardown.
