Subject: [PATCH v2 05/10] efi.h: Add efi_image_loaded_t

From: Matt Fleming <matt.fleming@...ux.intel.com>

Add the EFI loaded image structure and protocol guid which are
required by the x86 EFI boot stub. The EFI boot stub uses the
structure to figure out where it was loaded in memory and to pass
command line arguments to the kernel.

v2: use __aligned_u64 because x86 only aligns 64-bit data types on a
   4-byte boundary unless instructed otherwise.
