mv643xx_eth: Check ETH_INT_CAUSE_STATE bit

Browse Source 
Commit 468d09f894 masked the "state"
interrupt (bit 20 of the cause register). This results in Radstone's
PPC7D repeatedly re-entering the interrupt routine, locking up the
board. The following patch returns the required handling for this
interrupt.
