board-m7:Cleanup and some adjustments
Some code cleanup and some i2c bus clocks adjustment. Basically, idea is from @poondog but his reference is from Mako, I got my values from Samsung's i9505 source and cross-checked with Oppo-N1 source since both Devices uses same SoC and platform(Snapdragon 600).

board-m7-gpu:Boost GPU frequencies
I highly discourage heavy Overclocking since you can barely see the difference from stock. Just apply a hefty boost without that much of an impact on heat and performance.
