[PATCH 05/10 V3] omap3: pm: sr: replace get_opp with freq_to_opp

[Nishanth Menon <nm@ti.com>]

SmartReflex implements a get_opp to search through the opp table,
replace it opp_is_valid to verify the OPPs and getting the opp_id.

NOTE: usage of opp_id is deprecated and this introduces the following
warnings:
arch/arm/mach-omap2/smartreflex.c: In function 'get_vdd1_opp':
arch/arm/mach-omap2/smartreflex.c:160: warning: 'opp_id' is deprecated (declared at arch/arm/plat-omap/include/plat/opp.h:33)
arch/arm/mach-omap2/smartreflex.c: In function 'get_vdd2_opp':
arch/arm/mach-omap2/smartreflex.c:174: warning: 'opp_id' is deprecated (declared at arch/arm/plat-omap/include/plat/opp.h:33)
