firmware: arm_sdei: add SDEI_EVENT_SIGNAL support
Add sdei_event_signal(), a thin wrapper over the SDEI_EVENT_SIGNAL call
(DEN0054) that makes the software-signalled event (event 0) pending on a
target PE -- delivered NMI-like even when that PE has interrupts masked.
It takes no locks, so it is safe to call from NMI / crash context.
