[PATCH 2/5] ARM: OMAP3+: hwmod: Add AM33XX HWMOD data for davinci_mdio

[Richard Cochran]

From: Mugunthan V N <mugunthanvnm at ti.com>

This patch adds minimal hwmod support for davinci mdio driver. This patch
requires rework on parent child relation between cpsw and davinci mdio
hwmod data to support runtime PM.
