x86: make LOAD_FROM_32_BIT visible for platforms
This option is useful not only for development, but for the platforms where U-Boot is run from custom ROM bootloader. For example, Intel Edison is that board. Make this option visible that platforms can select it if needed. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
