ipq40xx: fix phy interrupt setting

This patch fixes a problem that was discovered during DSA
development. On the MR33, the link change events from the
external AR8035-PHY would never make it to the qca8k driver.

The issue turned out to be a misplaced memcpy that was copying
over the zero-initialized irq table, when it should have been
set to PHY_POLL. Hence this patch moves the memcpy after the
array has been initialized.
