ARM: dts: koelsch: 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, 75, 110, 115200015000002000000, and
        4000000 bps,
      - Perfect match for standard 50-460800, and 9216000 bps.
      - More accurate 576000 bps.
  - HSCIF:
      - Supports now 50, 75, 110, 134, 150, and 200 bps,
      - Perfect match for standard 50-460800, and 9216000 bps.
      - More accurate 576000, 115200030000003500000, and 4000000
bps.
