arm64: dts: freescale: imx{91,93}-phycore-som: Adjust PHY RST drive-strength
According to measurements, the PHY reset signal shows an overshoot on
the rising edge that exceeds the specified limits (max 2.1V) when using
X4 strength on ENET2_RXC. Reduce drive-strength to X1 to decrease the
overshoot and bring signal within specification limits.
