[PATCH] mailbox: apple: Keep IRQs active in suspend

[Hector Martin]

Some consumers (notably SMC) need to be wakeup sources for s2idle,
so the IRQs need to stay enabled during suspend. We expect
consumers to properly suspend coprocessors such that no IRQs would
be triggered where not necessary, so this can be done unconditionally.
