arm64: dts: renesas: rzg2l-smarc: Enable DU and link with DSI

Enable DU and link with DSI on RZ/{G2L,G2LC,V2L} SMARC EVK.

Move DSI port properties from board dtsi to SoC dtsi and then link with DU
and after that enable DU on the board dtsi.

arm64: dts: renesas: rz-smarc: Use versa3 clk for audio mclk

Currently audio mclk uses a fixed clk of 11.2896MHz (multiple of 44.1kHz).
Replace this fixed clk with the programmable versa3 clk that can provide
the clocking to support both 44.1kHz (with a clock of 11.2896MHz) and
48kHz (with a clock of 12.2880MHz), based on audio sampling rate for
playback and record.

arm64: dts: renesas: rzg2lc-smarc: Include SoM DTSI into board DTS

Move including the rzg2lc-smarc-som.dtsi from the carrier board
rzg2lc-smarc.dtsi to the actual RZ/G2LC SMARC EVK board dts
r9a07g044c2-smarc.dts. Also move the SW1 related macros along with
PMOD1_SER0 to board dts so that we have all the configuration options
in the same file.

This patch is to keep consistency with other SMARC EVKs (RZ/G2L, RZ/G2UL)
and it makes sense not include the SoM into the carrier board as we might
in future have a different carrier board with the same SoM.
