[PATCH 7/8] ARM: dts: imx7[d]-mba7: add Ethernet PHY IRQ support

Fri Nov 8 05:49:25 PST 2024
The regulator-fec*-pwdn regulators were used to deassert the PWDN signal
of ethernet PHY, e.g. not powering. This is not necessary as the line
has a pull-up already.
Instead of the combo pad of the PHY for IRQ support.
