Our policy is that we don't introduce new pinctrl nodes that are not
used by any board to avoid bloating the DT too much with unused nodes.

If you have a board using it, please submit that change as well.

OK, I agree.

However, this pinmux is only useful in case PA5 is assigned for PWM.
PA5 is commonly used for UART0_RX, so I'd like to add UART1 node into 
*.dts and disable it (status = "disabled"). Does it make sense?
