dt-bindings: i2c: qcom,i2c-qup: Document power-domains
Similar to qcom,geni-i2c, for i2c-qup we need to vote for performance
states on the VDDCX power domain to ensure that required clock rates
can be generated correctly.
I2C is typically used with a fixed clock rate, so a single required-opp
is sufficient without a full OPP table (unlike spi-qup for example).
