[RESEND PATCH 00/16] PCI: Use FIELD_MODIFY() to simplify bitfield operations

[Hans Zhang <18255117159@163.com>]

Replace open-coded bitmask clear + FIELD_PREP() sequences with the
dedicated FIELD_MODIFY() macro.  FIELD_MODIFY() performs the same
operation but is shorter, less error-prone, and includes compile-time
checks to prevent field overflow.

This series touches the PCI core, PCIe extended capabilities (PTM, IDE,
TPH, MSI, REBAR, IOV, CardBus), and several DesignWare-based and
other PCI host controllers.  No functional change is intended.

The patches are split per subsystem or per driver to ease review:

Hi, If the Maintainers think it's not necessary, please ignore it.
