[PATCH 00/22] usb: xhci: rework xHCI Port macros

[Niklas Neronin <niklas.neronin@linux.intel.com>]

Rework xhci-port.h to standardize how USB Port register macros are
defined and used.

Field macros are restricted to describing bit masks only, while the common
FIELD_* helpers are used to extract, set, and update field values.
This removes custom helpers and consolidates bitfield handling into a
single, well-established mechanism.

Other changes include:
- Renaming macros to follow the xHCI specification.
- Relocating USB Port macros to xhci-port.h
- Updating bit field comments and format.
- Adding missing bit/macros.

Why are there 22 patches when many make similar changes?
  The series is intentionally split to make review easier by keeping each
  patch focused and manageable. If preferred, the patches can be combined
  after review without issues.
