ARM: dts: porter: 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. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
