On i.MX8MM-EVK with PCA953x I2C GPIO expander driver enabled, one is
greeted with this warning:
WARNING: pca953x pca64160: Failed to get 'vcc' regulator (ignored).
We don't have a PMIC driver in barebox proper and assume that all
relevant regulators are already enabled by the prebootloader, so note
that in the device tree.
