[v3,2/3] net: phy: make phy_enable_interrupts() non-static

Currently, phy_disable_interrupts() allows to disable interrupts without
freeing them. However, the only exported function to re-enable them is
phy_request_interrupt(), which also requests them again. It should be
possible to re-enable interrupts without re-allocating them.

This is required for lan78xx.c where we want to enable/disable the phy
interrupts during lan78xx_link_status_change().
