net: ipa: don't assume 8 modem routing table entries

Currently all platforms are assumed allot 8 routing table entries
for use by the modem. Instead, add a new configuration data entry
that defines the number of modem routing table entries, and record
that in the IPA structure.

net: ipa: fix build

After commit 2c7b9b936bdc ("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.

net: ipa: move configuration data files into a subdirectory

Reduce the clutter in the main IPA source directory by creating a
new "data" subdirectory, and locating all of the configuration data
files in there.
