[U-Boot] [U-Boot, 07/15] spl: atf: introduce spl_invoke_atf and make bl31_entry private

[Kever Yang <kever.yang@rock-chips.com>]

Hi Philipp,

     This patch use fdt_addr as plat_params, break the compatible with 
upstream

ATF, and get error:

"ERROR:   not expected type found 6410029648624618960"

The ATF do have a requirement for plat_params structure, and fdt_addr 
does not match this:

/* common header for all plat parameter type */
struct bl31_plat_param {
 >-------uint64_t type;
 >-------void *next;
};


Thanks,
- Kever
