[PATCH v1 2/6] arm64: dts: imx8mp-var-som: Remove PCA9534 GPIO expander

[Stefano Radaelli]

The VAR-SOM-MX8MP module does not include the PCA9534 GPIO expander nor
the LED connected to it. These components are present only on the
Symphony carrier board and may vary depending on the final carrier
design.

Since the PCA9534 is not part of the SOM hardware, its node and related
LED definition do not belong in the SOM dtsi and are removed.
