mpc85xx: define reset-delay for WS-AP3825i eth PHY
The WS-AP3825i uses Atheros PHYs which according to the datasheet require the reset to be asserted for at least 1 ms. This fixes broken eth1 upon soft-reboot. eth0 is no affected, as the ifup / ifdown cycle in preinit prevents this issue from happening when the system is ready. Reported-by: Tom Herbers <freifunk@tomherbers.de> Signed-off-by: David Bauer <mail@david-bauer.net> (cherry picked from commit 8b3c313515c1ae37be9d61a4e92c4bf4b43f605f)
