[PATCH 08/17] OMAP2+: powerdomain: add voltagedomain to struct powerdomain

[Kevin Hilman <khilman@ti.com>]

Each powerdomain is associated with a voltage domain.  Add an entry to
struct powerdomain where the enclosing voltagedomain can be
referenced.

Modeled after similar relationship between clockdomains and powerdomains.
