[PATCH 4/8] OMAP3: PM: Adding smartreflex hwmod data

[Thara Gopinath <thara@ti.com>]

This patch adds the smartreflex hwmod data for OMAP3430
and OMAP3630. A dev_attr is also added to the hwmod
structure for each smartreflex module which contains
SoC specific info like the efuse offsets, test n-values
etc.
