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.
