acpi/ghes: better handle source_id and notification
GHES has two fields that are stored on HEST error source blocks associated with notifications: - notification type, which is a number defined at the ACPI spec containing several arch-specific synchronous and assynchronous types; - source id, which is a HW/FW defined number, used to distinguish between different implemented sources. There could be several sources with the same notification type, which is dependent of the way each architecture maps notifications. Right now, build_ghes_v2() hardcodes a 1:1 mapping between such fields. Move it to two independent parameters, allowing the caller function to fill both.
