[U-Boot] [U-Boot, v5, 11/18] arm: make save_boot_params_ret prototype visible for AArch64

[Philipp Tomsich]

> The save_boot_params_ret() prototype (for those of us, that have a

> previously only defined for !defined(CONFIG_ARM64).
> 
> This moves the declaration to a common block to ensure the prototype
> is available to everyone that might need it.
