[PATCH 2/6] ARM: OMAP AM33xx: voltagedomain: Add voltage domain data

[Paul Walmsley <paul@pwsan.com>]

From: Vaibhav Hiremath <hvaibhav@ti.com>

Currently dummy voltage domain data is being created
in order to succeed boot process, nothing has been done
w.r.t actual hardware (voltage control).

Also, hook up the AM33XX voltage domain to OMAP framework.
