Subject: [PATCH 4/8] arm64: dts: imx8mm-kontron: Fix reg_rst_eth2 and reg_vdd_5v regulators

From: Frieder Schrempf <frieder.schrempf@...tron.de>

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.

Fixes: 21c4f45b335f ("arm64: dts: Add the Kontron i.MX8M Mini SoMs and baseboards")
