OMAP2+: voltage: keep track of powerdomains in each voltagedomain
When a powerdomain is registered and it has an associated voltage domain,
add the powerdomain to the voltagedomain using voltdm_add_pwrdm().
Also add voltagedomain iterator helper functions to iterate over all
registered voltagedomains and all powerdomains associated with a
voltagedomain.
Modeled after a similar relationship between clockdomains and powerdomains.
