Increase lowest GPU step for 1400MHz devices

Devices using the 1400MHz Exynos 4210 are using 1280*800 screens. This
is a much bigger resolution than the Galaxy S2. 100MHz as the lowest GPU
step is too low for these devices, resulting in lag. Bump it up to
134MHz.

mali: pick the right GPU voltage table for 1400MHz devices, restore thresholds

8-level table was always used, resulting in increased voltages for
1400MHz devices. Now, the right table (5-level) can be picked at
runtime.

Restore the thresholds to stock value for more stable frequencies.
