[PATCH 8/8] arm64: dts: renesas: salvator: add a connection from adv748x codec (HDMI input) to the R-Car SoC

Not sure if all variants of the Salvator board have the HDMI decoder
chip (the ADV7482) connected to the SSI4 on R-Car SoC, as it is on
Salvator-X ES1, so the the ADV7482 endpoint and connection definitions
are placed in the board file.

I do assume though that all Salvator variants have the CLK_C clock line
hard-wired to the ADV7482 HDMI decoder, and remove it from the list of
clocks provided by the R-Car sound system.

The I2C wiring is also likely to persist across the variants (similar
to ak4613, connected to the same interface), so that is in the common
file.
