arm64: dts: renesas: rzg2l-smarc: Add support for enabling MTU3
Add support for PMOD_MTU3 macro to enable MTU3 node on RZ/{G2,V2}L SMARC EVK. The MTU3a PWM pins are muxed with spi1 pins and counter external input phase clock pins are muxed with scif2 pins. Disable these IPs when PMOD_MTU3 macro is enabled. Apart from this, the counter Z phase clock signal is muxed with the SDHI1 cd signal. So disable SDHI1 IP, when the counter Z phase signal is enabled.
