Increase build and test coverage by enabling support for more hardware
present on Renesas SoCs and boards:
  - R-Car CAN and CAN-FD controllers,
  - MSIOF SPI controllers,
  - ROHM BD9571 GPIO support,
  - R-Car MIPI CSI-2 receivers,
  - R-Car Video Input,
  - Renesas Fine Display Processors,
  - Renesas Digital Radio Interfaces,
  - R-Car Gen3 internal HDMI encoders,
  - Generic LVDS panel support,
  - Dumb VGA DAC Bridge support,
  - Thine THC63LVD1024 LVDS decoder bridges,
  - Synopsys Designware AHB Audio and CEC interfaces,
  - Renesas USBHS HCD support,
  - IDT VersaClock 5,6 devices,
  - Maxim max9611/max9612 ADCs,
  - ARM TrustZone CryptoCell security processors.

All of the above are modular, except for the VC5 clock driver, and the
SDR config gatekeepers.
