[PATCH 9/9 v2] omap3: pm: introduce 3630 opps

[Nishanth Menon <nm@ti.com>]

Introduce the OMAP3630 OPPs including the defined OPP tuples.

Further information on OMAP3630 can be found here:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606

OMAP36xx family introduces:
VDD1 with 4 OPPs, of which OPP3 & 4 are available only on devices yet
to be introduced in 36xx family. Meanwhile, VDD2 has 2 opps.

Range of OPPs supported by Devices(tentative)->
           |<-3630-600->| (default)
           |<-      3630-800  ->| (device: TBD)
           |<-      3630-1000             ->| (device: TBD)
H/w OPP-> OPP50 OPP100       OPP-Turbo   OPP1G-SB
VDD1      OPP1  OPP2         OPP3        OPP4
VDD2      OPP1  OPP2         OPP2        OPP2

Note:
a) TI h/w naming for OPPs are now standardized in terms of OPP50, 100,
   Turbo and SB. This maps as shown above to the opp IDs (s/w term).
b) For boards which need custom VDD1/2 OPPs, the opp table can be
   updated by the board file on a need basis after the
   omap3_pm_init_opp_table call. The OPPs introduced here are the
   official OPP table at this point in time.

Tested on: SDP3430, SDP3630
