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
