sky2: fix hang on shutdown (and other irq issues)
There are several problems with recent change to how IRQ's are setup.
* synchronize_irq in sky2_shutdown would hang because there
was no IRQ setup.
* when device was set to down, some IRQ bits left enabled so a
hardware error would produce IRQ with no handler
* quick link on Optima chip set was enabled without handler
* suspend/resume would leave IRQ on with no handler if device
was down
