 Added new register and bit definitions to enable Smartreflex driver integration.
 Also PRM_VC_SMPS_SA bit definitions' naming was changed to match the naming of
 other similar bit definitions.

-- removed EFUSE related ifdefs
+- Added E-fuse support: Use silicon characteristics parameters from E-fuse
 
 - added smartreflex_disable/enable calls to pm34xx.c suspend function.
 
 - Added "SmartReflex support" entry into Kconfig under "System type->TI OMAP
   Implementations". It depends on ARCH_OMAP34XX and TWL4030_CORE.
 
+- Added "SmartReflex testing support" Kconfig option for using hard coded
