Revert "cpufreq: smartmax: set default sample_rate to 50mS"

This reverts commit a71e1094e5dabbef35088706dbe80c5beab6fc44.
staging: android: logger: disabled at boot
msm_fb: Do not check for BLT when it is already enabled.

On some cases where BLT is enabled by default & the source dimensions require
BLT mode, it returns error.

Check if BLT is disabled before calculating if it should be enabled.

msm_fb: Skip writeback buffer init

Cases like "adb shell stop" & "adb shell start" cause the buffers to be
reinitialized, while the buffer has been already allocated.

Solves multiple issues, notably display crash no longer produces blank display.

msm_fb: Make sure the backlight is not set to 0 at boot
debug_mm: Only print pr_debug and pr_info if DEBUG.

Greatly reduces the logging of sound messages in the kernel. To enable the
logging, #define DEBUG before including debug_mm.h
rmt_storage: Decrease logging.

Mostly, this information is useless. When debugging is needed, #define DEBUG
at the start of this file should be added.
earlysuspend: speedup late resume (faster wakeup of the device)

Thanx to _2bad4u_ for the hint and dsc-team's repo I got the code from (https://github.com/dsc-team/dsc-team-kernel-project)
