efi: Fix efi_loaded_image_t::unload type

The ::unload field is a function pointer, so it should be u32 for 32-bit,
u64 for 64-bit. Add a prototype for it in the native efi_loaded_image_t
type. Also change type of parent_handle and device_handle from void * to
efi_handle_t for documentation purposes.

The unload method is not used, so no functional change.
