Hugo Villeneuve c8e6e06ede arm64: dts: imx8mn-var-som-symphony: add vcc supply for PCA9534
The following warning is shown when probing device:

    pca953x 1-0020: supply vcc not found, using dummy regulator

Define a new fixed 3.3v regulator for carrier board peripherals,
enabled by mosfet switch Q2 after the SOM_3V3 supply rises (no software
control).

Add this new regulator as vcc supply to the PCA9534 to silence the warning.
