ARM: dts: pfla02: increase phy reset duration
Increase the reset duration to ensure correct phy functionality. The
reset duration is taken from barebox commit 52fdd510de ("ARM: dts:
pfla02: use long enough reset for ethernet phy"):
Use a longer reset time for ethernet phy Micrel KSZ9031RNX. Otherwise a
small percentage of modules have 'transmission timeouts' errors like
barebox@Phytec phyFLEX-i.MX6 Quad Carrier-Board:/ ifup eth0
warning: No MAC address set. Using random address 7e:94:4d:02:f8:f3
eth0: 1000Mbps full duplex link detected
