  TI K3 pinctrl node.

  Pins can be configured using the following macro "K3_PINMUX(offset, value, mux_mode)".
  offset - the pin attribute register offset from the base address.
  value - one of the following:
    PIN_OUTPUT
    PIN_OUTPUT_PULLUP
    PIN_OUTPUT_PULLDOWN
    PIN_INPUT
    PIN_INPUT_PULLUP
    PIN_INPUT_PULLDOWN
  mux_mode - The mux mode for the pin, MUX_MODE_0 -> MUX_MODE_9.
  e.g. for AM62x the pinctrl base address is 0xf4000.
       The default UART0_RX pin is located at 0x000f41c8 (mux mode 0).
       So the configuration would be "K3_PINMUX(0x1c8, PIN_INPUT, MUX_MODE_0)".
