Add common handler in ghes for HW errors notified via hed(PNP0C33) driver.
1. Rename ghes_notify_sci() to ghes_notify_hed().
2. Rename struct notifier_block ghes_notifier_sci to
struct notifier_block ghes_notifier_hed.
3. Rename ghes_sci list to ghes_hed.
4. Make ghes_notify_hed as common handler for
notification types SCI, GSIV and GPIO.
