After commit 2c7b9b93 ("net: ipa: move configuration data files
into a subdirectory"), build of the ipa driver fails with the
following error:

drivers/net/ipa/data/ipa_data-v3.1.c:9:10: fatal error: gsi.h: No such file or directory

After the mentioned commit, all the file included by the configuration
are in the parent directory. Fix the issue updating the include path.
