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.
