[PATCH] platform: andes: Fix license to compatible GPL

[Xiang W]

Since platform/generic/include/andes/andes.h and
platform/generic/include/andes/andes_pma.h are licensed under the
GPL, any C files that use them should also be modified to comply
with the GPL. Otherwise, there may be potential legal issues.
