 - Add Ethernet clocks and resets on Renesas RZ/G3E
 - Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
  (R9A09G087) SoCs
 - Add Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
 - Add timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on
   Renesas RZ/V2N
 - Rework Module Stop and Power Domain support on the Renesas
   RZ/G2L family of SoCs (especially on RZ/G3S)
 - Add I3C clocks and resets on Renesas RZ/G3E
