	In order to allow events to be dynamically added, remove the existing static array of events and use a simply linked list of supported events. This allows us to move the cb_ops into this list and associated it with an event_id. Drivers can now register cb_ops before bringing up the sse core to handle additional events (platform ones for instance). sbi_sse_init() now allocates as many events as present in the linked list. Events can now be added with sbi_sse_add_event() which allows to add new supported events with some callback operations if any. If an event is not to be supported, then sbi_sse_add_event() should not be called. This approach currently consider that local events are to be supported on all harts (ie, they all support the same ISA or dependencies). If per-hart event availability needs to be supported, then, an is_supported() callback could be added later and called for each hart.

2024-04-05	lib: sbi: Add support for Supervisor Software Events extension	Clément Léger
	This extension [1] allows to deliver events from SBI to supervisor via a software mechanism. This extension defines events (either local or global) which are signaled by the SBI on specific signal sources (IRQ, exceptions, etc) and are injected to be executed in supervisor mode.
