Add Renesas R-Car R8A78000 X5H MDLC power domain and reset driver, which serves as a remap driver between DT power domain and reset IDs and SCMI power domain and reset IDs in case U-Boot runs on Cortex-A, and as a direct hardware access driver for RSIP. The R-Car X5H SCP firmware uses different SCMI power domain and reset IDs in different versions of the SCP firmware, which makes this remapping necessary. The SCMI base protocol version is updated for each new SCP firmware version, it is therefore possible to determine which SCP firmware version is running on the platform from the base protocol and then determine which remapping table to use for DT power domain and reset ID to SCMI power domain and reset ID remapping. Currently supported versions are SCP 4.28, 4.31, 4.32 . The DT power domain and reset ID to SCMI power domain and reset ID remap and call mechanism is simple. Unlike SCMI clock protocol driver, the SCMI reset and power domain protocol drivers register only a single device. This driver looks up that single device, obtains its reset or power domain ops, sets up struct reset_ctl or struct power_domain with remapped SCMI ID, and invokes operations directly on the device. In case of RSIP, all power domains are already enabled by BootROM or early SoC initialization code, the driver therefore only acts as a stub for the power domain part. The reset part operates as a direct hardware access reset driver. Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>

Enable support for the power domain driver class. Many SoCs allow

power to be applied to or removed from portions of the SoC (power

domains). This may be used to save power. This API provides the

means to control such power management hardware.
