We should probably have separate PIN_INPUT_3V3 and PIN_OUTPUT_3V3
dts macros that ensure that?

I'm in general no fan of such macros: it feels really awkward to have
to make that distinction in dts when doing pin config.

Note that if you're feeling really enthausiastic about putting in
effort to allow inputs to be disabled while staying clear of the
erratum, I think you can detect at runtime which I/O supplies are 3.3V
by inspecting this register:

#define CTRL_CQDETECT_STATUS    0x48140e00

OK and if really needed needed the SoC revision information can be
passed to pinctrl-singl.c in it's platform_data that we already have
in addition to the dts configuration. And then pinctrl-single.c could
modify the mask based on IO voltage and SoC revision.

I think we're already covered as the boards can override the pinctrl
function-mask in the board specific dts file if really needed :)
