efi_loader: clean up UEFI sub-system initialization
allow_unaligned(), switch_to_non_secure_mode(), and efi_init_obj_list() are called in sequence in multiple places. Move calls to allow_unaligned() and switch_to_non_secure_mode() to efi_init_obj_list(). Remove unused includes. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
