arm64: dts: imx8mm-kontron: Fix reset delays for ethernet PHY

Browse Source 
[ Upstream commit 315e7b884190a6c9c28e95ad3b724dde9e922b99 ]

According to the datasheet the VSC8531 PHY expects a reset pulse of 100 ns
and a delay of 15 ms after the reset has been deasserted. Set the matching
values in the devicetree.
