default-suites.conf: Make sure we use fr codec with IPA dyn TS

IPA style dynamic timeslots (TCH/F_PDCH) support only TCH/F and thus
only full rate codecs are to be used.

On the other hand, OSMO style dynamic timeslots (TCH/F_TCH/H_PDCH) can
use both full rate and half rate, so no need to be restrictive there.
