arm64: dts: renesas: Add initial device tree for RZ/G2LC SMARC EVK
Add basic support for the RZ/G2LC SMARC EVK (based on R9A07G044C2):
- memory
- External input clock
- SCIF
- GbEthernet
- Audio Clock
It shares the same carrier board with RZ/G2L, but the pin mapping is
different. Disable the device nodes which are not tested and delete the
corresponding pinctrl definitions.
