[ Upstream commit cdbc6e2d8108bc47895e5a901cfcaf799b00ca8d ]

The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().

Only compile tested.
