This patch series introduces two new features, enhances existing
functionalities, and adds NVL support to the intel_pmc_core driver.

The first three patches add new attributes to improve Package C-state
debugging. The fourth and fifth patches refine current functionality
for better support. The sixth patch enables the intel_pmc_core driver
retrieves PMC information only for available PMCs. Finally, the last
patch adds support for Nova Lake platforms.

v2->v1:
- Add a patch to use __free(pci_dev_put) in pmc_core_punit_pmt_init().
- When using scoped base cleanup method, move variable declaration and
assignment in one place.
- Simplifies logic and remove unneeded offset variables.
- Create common helper function to used by pmc_core_pkgc_ltr_blocker_show()
and pmc_core_pkgc_blocker_residency_show()
- Add num_pmcs field in pmc_dev_info struct to store the number of PMCs
available in the platform.
- Use lowercase letter for variable in nvl.c().
- Fix typo.
