[PATCH v2 0/3] New vendor support and optimizations for DWC PCIe PMU

[Yicong Yang]

This patchset mainly enable the DWC PCIe PMU on our platform (Patch 1/3).
Besides do some optimization and refactor:
- Patch 2/3 extend the monitoring limit on platforms with narrowed counter width (< 64 bit)
- Patch 3/3 switch the driver to use the faux device interface

Change since v1:
- always enable hrtimer for updating narrowed counters on affected platform
- refine the commints and fix styles per Jonthan, thanks.
