firmware: arm_sdei: Add driver for Software Delegated Exceptions
The Software Delegated Exception Interface (SDEI) is an ARM standard for registering callbacks from the platform firmware into the OS. This is typically used to implement firmware notifications (such as firmware-first RAS) or promote an IRQ that has been promoted to a firmware-assisted NMI. Add the code for detecting the SDEI version and the framework for registering and unregistering events. Subsequent patches will add the arch-specific backend code and the necessary power management hooks. Only shared events are supported, power management, private events and discovery for ACPI systems will be added by later patches.
