arm64: dts: renesas: Add initial device tree for RZ/G2UL Type-1 SMARC EVK

Add basic support for RZ/G2UL SMARC EVK (based on R9A07G043U11):
- memory
- External input clock
- CPG
- DMA
- SCIF

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.
