msm: acpuclock-8974: Modify L2 table for 8974

Currently 1.26 GHz and 1.49 GHz in the L2 tables for 8974
map to 800 MHz DDR. With this change the above frequencies
now get mapped to 614 MHz DDR. This change maps the above
two frequencies to lower DDR and will thereby help save power
for use cases which spend majority of time at above frequencies.
