cpufreq: ondemand: Eliminate the dead band effect in low load

Currently, ondemand calculates the target frequency proportional to load
using the formula:
	Target frequency = C * load
	where C = policy->cpuinfo.max_freq / 100

Though, in many cases, the minimum available frequency is pretty high and
the above calculation introduces a dead band from load 0 to
100 * policy->cpuinfo.min_freq / policy->cpuinfo.max_freq where the target
frequency is always calculated to less than policy->cpuinfo.min_freq and
the minimum frequency is selected.

For example: on Intel i7-3770 @ 3.4GHz the policy->cpuinfo.min_freq = 1600000
and the policy->cpuinfo.max_freq = 3400000 (without turbo). Thus, the CPU
starts to scale up at a load above 47.
On quad core 1500MHz Krait the policy->cpuinfo.min_freq = 384000
and the policy->cpuinfo.max_freq = 1512000. Thus, the CPU starts to scale
at load above 25.

Change the calculation of target frequency to eliminate the above effect using
the formula:

	Target frequency = A + B * load
	where A = policy->cpuinfo.min_freq and
	      B = (policy->cpuinfo.max_freq - policy->cpuinfo->min_freq) / 100

This will map load values 0 to 100 linearly to cpuinfo.min_freq to
cpuinfo.max_freq.

Also, use the CPUFREQ_RELATION_C in __cpufreq_driver_target to select the
closest frequency in frequency_table. This is necessary to avoid selection
of minimum frequency only when load equals to 0. It will also help for selection
of frequencies using a more 'fair' criterion.

In tables below is presented the difference in selected frequency for specific
values of load without and with this patch. On Intel i7-3770 @ 3.40GHz:
