According to the BCM2835 ARM Peripherals document uart1 doesn't map to pins
36-39, but uart0 does.

Also, split into separate Rx/Tx and CST/RTS groups to match other uart nodes.

Fixes: 21ff843931b ("ARM: dts: bcm283x: Define standard pinctrl groups in the gpio node.")

These look good, too.  Thanks!
