thunderbolt: Clear registers properly when auto clear isn't in use

commit c4af8e3f upstream.

When `QUIRK_AUTO_CLEAR_INT` isn't set, interrupt masking should be
cleared by writing to Interrupt Mask Clear (IMR) and interrupt
status should be cleared properly at shutdown/init.

This fixes an error where interrupts are left enabled during resume
from hibernation with `CONFIG_USB4=y`.

Fixes: 468c49f4 ("thunderbolt: Disable interrupt auto clear for rings")
