arm64: dts: ti: k3-am64-tqma64xxl: add supply regulator for I2C devices

Describes the hardware better, and avoids a few warnings during boot:

    lm75 0-004a: supply vs not found, using dummy regulator
    at24 0-0050: supply vcc not found, using dummy regulator
    at24 0-0054: supply vcc not found, using dummy regulator
