The 4430 OPP table was being registered for all other OMAP4 variants
too, like 4460 and 4470 causing issues with cpufreq driver
enabled. 4460 and 4470 devices have different OPPs as compared to
4430, and they should be populated seperately. As long as that
happens, let the OPP table registeration happen only on 4430 device.

Almost all OMAP4 boards support OPP 800 MHz and OPP 1 GHz.
Enable them in OPP Table. For small minority of boards which use
OMAP4430-800 MHz device OPP 1GHz is not supported,
OPP 1GHz should be disabled from board file.

Since all voltage data is now centralized in oppxxx_data.c, we can replace
the values in the opp table with the macros used for voltage values.

This will avoid opp table and voltage layer having conflicting values.

This is a first pass at reorganizing mach-omap2/voltage.c:

- Separate almost all of the data from the code of mach-omap2/voltage.c.
  The code remains in mach-omap2/voltage.c.  The data goes into one
  of several places, depending on what type of data it is:

  - Silicon process/validation data: mach-omap2/opp*_data.c
  - VC (Voltage Controller) data: mach-omap2/vc*_data.c
  - VP (Voltage Processor) data: mach-omap2/vp*_data.c
  - Voltage domain data: mach-omap2/voltagedomains*_data.c

  The ultimate goal is for all this data to be autogenerated, the same
  way we autogenerate the rest of our data.

- Separate VC and VP common data from VDD-specific VC and VP data.

- Separate common voltage.c code from SoC-specific code; reuse common code.

- Reorganize structures to avoid unnecessary memory loss due to unpacked
  fields.

There is much left to be done.  VC code and VP code should be separated out
into vc*.c and vp*.c files.  Many fields in the existing structures are
superfluous, and should be removed.  Some code in voltage.c seems to be
duplicated; that code should be moved into functions of its own.  Proper
voltage domain code should be created, as was done with the powerdomain
and clockdomains, and powerdomains should reference voltagedomains.

to Rajendra Nayak <rnayak@ti.com> for finding and fixing some bugs
that prevented OMAP4 from booting:

His patch has been folded into this one to avoid breaking OMAP4
between patches.  Thanks also to Kevin Hilman <khilman@ti.com> for
finding and fixing a compile problem when !CONFIG_PM:

His patch has also been folded into this one to avoid breaking
!CONFIG_PM builds.

omap3 and omap4 opp_init should be made non-static to allow
for platform specific opp table tweaking. making these static
conflicts with the definition in pm.h(global) as well.
we include pm.h as well to ensure that there are no such prototype
conflicts with actual implementation in the future.

This patch adds OPP tables for OMAP4. New file has been added to keep
the OMAP4 opp tables and the registration of these tables with the
generic opp framework by OMAP SoC OPP interface.
