device: remove board_override_cmd_line() from sama5d3

[edgar-bonet]

This pull request addresses issue #126.

According to Nicolas Ferre, the Android-specific code in this function is not needed anymore. Then, this version of the function can be removed, and we can instead rely on the default, weak implementation defined in driver/load_kernel.c.

Incidentally, this fixes a bug, as this board_override_cmd_line() would return NULL unless CONFIG_LOAD_ANDROID was set.

Combined with Tony Han's patch to Config.in.kernel, this makes the Acqua board bootable by AT91Boostrap 4.
