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.
