Introduce the pfr_update driver which can be used for Platform Firmware Runtime code injection and driver update [1]. The user is expected to provide the EFI capsule, and pass it to the driver by writing the capsule to a device special file. The capsule is transferred by the driver to the platform firmware with the help of an ACPI _DSM method under the special ACPI Platform Firmware Runtime Update device (INTC1080), and the actual firmware update is carried out by the low-level Management Mode code in the platform firmware. This change allows certain pieces of the platform firmware to be updated on the fly while the system is running (runtime) without the need to restart it, which is key in the cases when the system needs to be available 100% of the time and it cannot afford the downtime related to restarting it, or when the work carried out by the system is particularly important, so it cannot be interrupted, and it is not practical to wait until it is complete.
