OMAP2+: powerdomain: add voltagedomain to struct powerdomain
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. Signed-off-by: Kevin Hilman <khilman@ti.com>
