This patch series is based on next-20220915.
Add minimal support for R-Car S4-8 Etherent Switch. This hardware
supports a lot of features. But, this driver only supports it as
act as an ethernet controller for now.

- patch [1/8] is for CCF.
- patch [2/8] and [3/8] are for Generic PHY.
- patch [4/8] through [6/8] are for Network Ethernet.
- patch [7/8] and [8/8] are for Renesas ARM64 SoC.

Changes from v1:
 https://lore.kernel.org/all/20220909132614.1967276-1-yoshihiro.shimoda.uh@renesas.com/ (local)
 - Separate Ethernet SERDES hardware block so that made a Generic PHY driver.
 - Separate PTP support into a patch as patch [6/8].
 - Fix dt-bindings of Ethernet Switch.
 - Remove module parameters from Ethernet Switch driver.
 - Wrote reverse christmas tree about local variables in all the code.
 - Improve error path handlings.
 - Add comment about the current hardware limitation.
 - Add comment about magic numbers about SERDES settings.
