cpufreq: Optimize cpufreq_frequency_table_verify()

cpufreq_frequency_table_verify() is rewritten here to make it more logical
and efficient.
 - merge multiple lines for variable declarations together.
 - quit early if any frequency between min/max is found.
 - don't call cpufreq_verify_within_limits() in case any valid freq is
   found as it is of no use.
 - rename the count variable as found and change its type to boolean.

Input: Send events one packet at a time

On heavy event loads, such as a multitouch driver, the irqsoff latency
can be as high as 250 us.  By accumulating a frame worth of data
before passing it on, the latency can be dramatically reduced.  As a
side effect, the special EV_SYN handling can be removed, since the
frame is now atomic.

This patch adds the events() handler callback and uses it if it
exists. The latency is improved by 50 us even without the callback.

Input: Improve the events-per-packet estimate

The events-per-packet estimate has so far been used by MT devices
only. This patch adjusts the packet buffer size to also accomodate the
KEY and MSC events.  Keyboards normally send one or two keys at a
time. MT devices normally send a number of button keys along with the
MT information.  The buffer size chosen here covers those cases, and
matches the default buffer size in evdev. Since the input estimate is
now preferred, remove the special input-mt estimate.

OMAPDSS: DISPC: Use FIR filters other than M19
Pass correct arguments to FIR filter selection.  Previously we
always ended up selecting M19 5-tap filter.

This should improve image quality of scaled layers.

OMAPDSS: DISPC: more precise scale limits checking
Use division with rounding-up when checking if maximum downscale ratio
was reached. This allows to avoid SYNC_LOST errors in case when small
amount of extra pixels or lines (usually 1-3) not taken into account

[IVAHD] Disable HWSUP mode and save power
Enabling HWSUP mode is somehow reducing the performance
of SL2 memory leading to increase in power consumption.
This patch disables it and advertises only SWSUP mode
which seems to improve performance and reduce power
consumed in AV record use-case.
