[PATCH 4/8] arm64: dts: imx8mm-kontron: Fix reg_rst_eth2 and reg_vdd_5v regulators
From: Frieder Schrempf <hidden>

From: Frieder Schrempf <redacted>
The regulator reg_vdd_5v represents the fixed 5V supply on the board which
can't be switched off. Mark it as always-on.
The regulator reg_rst_eth2 should keep the reset signal of the USB ethernet
adapter deassertet anytime. Fix the polarity and mark it as always-on.
