mali: Increase 100 MHz step to 108MHz to prevent lag on n7000
mali: Increase lowest to 134MHz and 4-step gpu DVFS control
asv: Change initcall level to an earlier stage

We cannot wait for all device_initcall's (And subsequently module_init calls) to
complete before doing the ASV level readout without doing silly workarounds in
those drivers, waiting for an uninitialized exynos_result_of_asv.

Just change the ASV driver initialization from device stage to subsys stage, as
it is not dependant on other drivers or modules.
mali: Initialize gpu defaults properly after ASV change commit
drivers: staging: LMK - Added screen on/off values & tuning
mm: writeback tweaks during screen on/off
mm: Tune some writeback values
init.d: Add some explanation for users
bcmdhd: Fix wifi tethering
drivers: video: s6e8aa0: Allow max brightness at 255
