msm: clock-8960: Support 8960ab gfx speed-push

Certain 8960ab devices have a graphics core capable of running at 440MHz.
These devices are distinguished from regular 8960ab devices through a
speed bin attribute located in efuse.

Configure PLL3 to provide 880 Mhz, which is divided down to the rate
graphics requires.
