[U-Boot] [PATCH 1/2] efi_loader: typedef struct efi_object *efi_handle_t

All our handles point to a struct efi_object. So let's define the
efi_handle_t accordingly. This helps us to discover coding errors much
more easily. This becomes evident by the corrections to the usage of
handles in this patch.
