[U-Boot] [PATCH] sunxi: disable Pine A64 model detection code on non-A64 SoCs

[Icenowy Zheng]

The Pine A64 Plus/non-Plus model detection code is now built on all
64-bit ARM SoCs, even if the code cannot be triggered when H5/H6 is in
use.

Disable them when the SoC is not A64 by use #ifdef to wrap them.

On GCC 7.3.1 this makes the size of the function reduces 184 bytes, and
saves a 104 byte strstr() function, then makes SPL on H6 succeed to
build.
