usb: typec: fusb302: Revert incorrect threaded irq fix
The fusb302 irq handler has been carefully optimized by Hans de Goede in
commit 207338ec5a27 ("usb: typec: fusb302: Improve suspend/resume
handling"). A recent 'fix' undid most of that work to avoid a virtio-gpio
driver bug.
This reverts the incorrect fix, since it is of very low quality. It
reverts the quirks from Hans change (and thus reintroduces the problems
fixed by Hans) while keeping the overhead from the original change.
The proper fix to support using fusb302 with an interrupt line provided
by virtio-gpio must be implemented in the virtio driver instead, which
should support disabling the IRQ from the fusb302 interrupt routine.
