Smaller OPP table, disable OCFREQ_12

In all prior builds since the merge to Hybrid kernel LTE 4G was broken for US users. As this issues seems to be related to PM we try to set a smaller OPP table but keep OPP25 (100mhz). A total count of 7 OPPs should keep everything in track - if it works we can extend the table step by step and see when it starts to break the connection..
