msm: acpuclock-krait: NULL terminate L2 table for find_cur_l2_level()

find_cur_l2_level() assumes that the L2 table is NULL terminated
when it has never been terminated. Therefore, if the rate that is
read from the hardware during boot is not found in the table we
will run off the end of the table and read potential junk values.
NULL terminate all the L2 tables so that the loop in
find_cur_l2_level() is guaranteed to terminate.

msm: acpuclock-krait: Keep the secondary MUX input fixed

With use of the QSB clock source recently eliminated, only one
input of the secondary clock MUX is used on any target. Since
there is overhead involved reprogramming this MUX when changing
the CPU and L2 frequencies, change the code to just program the
MUX at boot.  Most noticeably, this removes a 1us delay from
every CPU and L2 frequency switch.

msm: acpuclock-8064: Lower VDD_DIG voltage vote for L2 at 384MHz

New characterization data shows that vdd_dig voltage for L2@384MHz
can be lowered to 0.95v. Update the data in this patch.
