[PATCH 1/2] arm64: dts: renesas: rzg2ul-smarc: Enable RSPI1 on carrier board

[Biju Das]

RSPI1 (SPI1) interface is available on PMOD0 connector (J1) on the
carrier board.  This patch adds pinmux and spi1 nodes to the carrier
board dtsi file and drops deleting pinctl* properties from board
DTS file.
