Subject: [PATCH v3 03/10] acpi: Introduce SSE in HEST notification types

Introduce a new HEST notification type for RISC-V SSE events.
The GHES entry's notification structure contains the notification
to be used for a given error source. For error sources delivering
events over SSE, it should contain the new SSE notification type.
