6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonas Karlman jonas@kwiboo.se
[ Upstream commit 7affb86ef62581e3475ce3e0a7640da1f2ee29f8 ]
UAR0 CTS/RTS is not wired to any pin and is not used for the default serial console use of UART0 on ROCK Pi S.
Override the SoC defined pinctrl props to limit configuration of the two xfer pins wired to one of the GPIO pin headers.
