[PATCH] ARM: bcm2835: dts: fix uart1 pinctrl node name

Downstream kernel uses pins 32, 33 as UART0 (PL011) Rx/Tx to communicate with
the Bluetooth chip. So ALT3 of these pins is most likely not CTS/RTS. Change
the node name to reflect that.

With this change in place, adding

  &uart0 {
	 pinctrl-names = "default";
	 pinctrl-0 = <&uart0_gpio32 &gpclk2_gpio43>;
	 status = "okay";
  };

to bcm2837-rpi-3-b.dts does the right thing on my Raspberry Pi 3.

Should uart0_gpio30 be renamed to uart0_ctsrts_gpio30?
