For devices in the RZ/G2L family, we have so far relied on U-Boot
correctly configuring the Ethernet interfaces in RGMII mode with
PVDD=1.8V before the kernel is booted. Instead, the required
configuration should be described in the device tree and activated
within the pinctrl driver.
Changes v1-v2:
* Rebased on next-20240611.
* Changed the approach taken in the pinctrl patches to be compatible
with changes made by Prabhakar for RZ/V2H support. I haven't picked
up Reviewed-by tags on these patches as they've changed a lot.
* Clarified that patch 6/9 also affects RZ/Five.
* No major changes to the dts patches so I've picked up Geert's
Reviewed-by tags for these.
