This series adds QMP PCIe PHY support for the Qualcomm Hawi SoC. The Hawi
platform features two PCIe PHY configurations: Gen3 x2 and Gen4 x1.

The Gen3 x2 PHY uses v10 register definitions, while the Gen4 x1 PHY uses
v10.60 register definitions.

The series adds:
- device tree bindings
- v10 register offset headers
- v10.60 register offset headers
- driver support with PHY initialization tables for both configurations

Overlap:
The series has overlap with "phy: qcom: Introduce USB support for Hawi"
by Ronak Raheja (see link [1]). Both patch series introduce a subset of
v10 registers (this series for PCIe and Ronak's for USB). I have
coordinated with Ronak regarding the overlap, and we can update the
series to resolve any overlap based on the order of merging.

Changes in v3:
- Squashed v10 register offsets into a single change
- Squashed v10.60 register offsets into a single change
- Removed USB mentions from header comments; offsets are PCIe-specific
- Reused the tx offset for the v10.60 combined txrx module instead of
  introducing a separate txrx offset
- Link to v2: https://patch.msgid.link/20260604-hawi-phy-pcie-v2-0-be90...

Changes in v2:
- Rebased onto v7.1-rc6
- Patch 1: no change (Reviewed-by carried forward)
- Patch 9: rename QPHY_PCIE_V10_60_PCS_PCS_TX_RX_CONFIG to
  QPHY_PCIE_V10_60_PCS_TX_RX_CONFIG to be consistent with the
  naming convention used in previous pcs-pcie headers
- Patch 10: update usage of renamed macro
- Link to v1: https://patch.msgid.link/20260508-hawi-phy-pcie-v1-0-237b...
