dt-bindings: input: cyttsp5: document vddio-supply
The Samsung touchscreen controllers are often used with external pull-up
for the interrupt line and the I2C lines, so we might need to enable
a regulator to bring the lines into usable state. Otherwise, this might
cause spurious interrupts and reading from I2C will fail.
Document support for a "vddio-supply" that is enabled by the cyttsp5
driver so that the regulator gets enabled when needed.
