The variable i is removed by commit ded84337
"[CPUFREQ] db8500: remove unneeded for loop iteration over freq_table",
but current code to print available frequencies still uses the i variable.
Thus add the i variable back to fix below buld error:

  CC      drivers/cpufreq/db8500-cpufreq.o
drivers/cpufreq/db8500-cpufreq.c: In function 'db8500_cpufreq_init':
drivers/cpufreq/db8500-cpufreq.c:123: error: 'i' undeclared (first use in this function)
drivers/cpufreq/db8500-cpufreq.c:123: error: (Each undeclared identifier is reported only once
drivers/cpufreq/db8500-cpufreq.c:123: error: for each function it appears in.)
make[2]: *** [drivers/cpufreq/db8500-cpufreq.o] Error 1
make[1]: *** [drivers/cpufreq] Error 2
make: *** [drivers] Error 2

This patch also fixes using uninitialized i variable as array index.

This adds support for the 200 MHz frequency mode of the
DB8500 SoC, and prints the available frequencies at init
time.

Don't know why to do the loop iteration here. It looks unneeded.

The same clock is used for all cpus so we must notify the frequency change
for each one in order to update the configuration of all twd clockevents.

change since V1:
* use policy->cpus instead of cpu_online_mask

Now that we have a shared API between the DB8500 and DB5500
PRCMU's, switch to using this neutral API instead. We delete the
parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will
be diverted to respective driver. Common registers are in
dbx500-prcmu-regs.h and common accessors and defines in
<linux/mfd/dbx500-prcmu.h> This way we get a a lot more
abstraction and code reuse.

This updates the ux500 cpufreq driver to the new interface from the
updated DB8500 PRCMU

As part of the ARM arch subsystem migration, move the DB8500
cpufreq driver to drivers/cpufreq as discussed with Dave Jones. The
Makefile is not updated in order to avoid cross-subsystem conflicts
for this file in merges.

We have decided that this function arbiter fits better in the MFD
subsystem. Since we need to concatenate the split header files we move
it basically like this:

mv mach-ux500/prcmu-db8500.c drivers/mfd/db8500-prcmu.c
mv mach-ux500/include/mach/prcmu-defs.h include/linux/mfd/db8500-prcmu.h
mv mach-ux500/include/mach/prcmu-regs.h drivers/mfd/db8500-prcmu-regs.h
mach-ux500/include/mach/prcmu.h >> include/linux/mfd/db8500-prcmu.h
rm arch/arm/mach-ux500/include/mach/prcmu.h

Then we update different #include statements and Makefile orders etc
to make the PRCMU driver compile, link and boot in the new place
without really changing any code.
