apexqtmo: introduce more aggressive thermal throttling

Due to the sub-standard chips used on some SoC revs, some apexqtmo
devices have a need for higher levels of thermal throttling. Break the
MSM8260a out from the rest of the MSM8960's by platformid, and assign
more aggressive thermal throttling if an affected cpu is detected.
