[PATCH] ARM: i.MX8M: evk: mark PMIC barebox,allow-dummy-supply

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

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.
