arm64: dts: salvator-x: Enable SCIF_CLK frequency and pins
Add and enable the external crystal for the SCIF_CLK and its pinctrl, to
be used by the Baud Rate Generator for External Clock (BRG) on (H)SCIF.
This increases the range and accuracy of supported baud rates:
- SCIF:
- Supports now 50, 230400, 460800, 500000, and 921600 bps,
- Perfect match for standard 50-460800, and 9216000 bps.
- HSCIF:
- Supports now 50, 75, and 110 bps,
- Perfect match for standard 50-460800, and 9216000 bps.
