tegra: hwpm: add clk-rst HALs, update HAL validation

Browse Source 
- 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.
