This small series introduce some cleanup and support for
clock and reset of Airoha AN7583.

The implementation is similar to EN7581 but AN7583 introduce
new reset and more clock divisor support.

Changes v6:
- Address bot suggestion for DT patch
- Add further information on chip-scu phandle
- Add dedicated PERSTOUT reset and PCIE_HB reset

Changes v5:
- Rebase on top of linux-next
- Drop even more patch to reduce patch delta
- Make chip-scu specific to AN7583
  Link: https://lore.kernel.org/all/20260528190000.9164-1-ansuelsmth@gmail.com

Changes v4:
- Add review tag for DT patch
- Fix clock patch to use en7581-chip-scu compatible
- Drop PCIE SCU SSR write

Changes v3:
- Drop .set_rate patch (will be proposed later)
- Drop chip-scu binding and related patch
  Link: https://lore.kernel.org/all/20251106195935.1767696-1-ansuelsmth@gmail.com

Changes v2:
- Add .set_rate support
- Rework DT to EN7581 implementation (clock driver is parent)
- Add additional cleanup patch
- Merge binding with schema patch
- Add chip_scu phandle

Document support for Airoha AN7583 clock. This is based on the EN7523
clock schema with the new requirement of the "airoha,chip-scu".

Add additional binding for additional clock and reset lines.

Airoha AN7583 SoC will use the same logic used by Airoha EN7581 SoC to
register clocks. Generalize it to register clocks defined in soc_data.

Add the clocks definition in EN7581 SoC to support this new implementation.

Add support for Airoha AN7583 clock and reset.

Airoha AN7583 SoC have the same register address of EN7581 but implement
different bits and additional base clocks. Also reset are different with
the introduction of 2 dedicated MDIO line and drop of some reset lines.
