For correct handling of protocols by the EFI block driver we need to
open protocols BY_DRIVER or BY_CHILD_CONTROLLER. By moving the event
registration for block devices to the block device driver we can add
the EFI Driver Binding protocol interface as context to the events.
Later patches will use the driver handle from this protocol as agent
handle.

This patch only creates an empty init function that will be filled with code later on. The function needs to be called before any EFI block devices are used. Move the efi_driver_init() call to early init.
