Subject: [PATCH 5/6] efi: fix type of unload field in efi_loaded_image_t

From: Arvind Sankar <nivedita@...m.mit.edu>

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.
