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.

Based on schematics, tested with remote access.

v4:
  - Change one-line summary prefix to match current arm-soc practices,

v3:
  - New.
