thunderbolt: Clear registers properly when auto clear isn't in use
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: 468c49f44759 ("thunderbolt: Disable interrupt auto clear for rings")
