arm64: dts: fsl-imx8mm-verdin: eth phy: improve startup
After the Ethernet PHY supply is enabled an RC holds the reset asserted
for about 120 ms. Reduce the time waited from 1000 ms to 200 ms which
should account for any possible tolerance.
U-Boot enables the PHY supply, switching it off in Linux with the RGMII
pins allready muxed creates backfeeding, thus set regulator-boot-on.
