That's the naming convention followed in most of opp core, but few
routines didn't follow this, fix them.

free-table routines are opposite of init-table ones, and must be named
to make that clear. Opposite of 'init' is 'exit', but those doesn't suit
really well.
Replace 'init' with 'add' and 'free' with 'remove'.

OPP layer now supports freeing of OPPs and we should free them once they aren't
useful anymore.

This patch adds IKS (In Kernel Switcher) support to cpufreq driver.
This creates a combined freq table for A7-A15 CPU pairs. A7 frequencies
are virtualized and scaled down to half the actual frequencies to
approximate a linear scale across the combined A7+A15 range. When the
requested frequency change crosses the A7-A15 boundary a cluster switch
is invoked.
Based on earlier work from Sudeep KarkadaNagesha.

The cpu_to_cluster() function may be used by glue drivers, so it's
better to keep it in arm_big_little.h.

big LITTLE is ARM's new Architecture focussing power/performance needs of modern
world. More information about big LITTLE can be found here:
http://www.arm.com/products/processors/technologies/biglittleprocessing.php
http://lwn.net/Articles/481055/
In order to keep cpufreq support for all big LITTLE platforms simple/generic,
this patch tries to add a generic cpufreq driver layer for all big LITTLE
platforms.
The driver is divided into two parts:
- Core driver: Generic and shared across all big LITTLE SoC's
- Glue drivers: Per platform drivers providing ops to the core driver
This patch adds in a generic glue driver which would extract information from
Device Tree.
Future SoC's can either reuse the DT glue or write their own depending on the
need.
