Subject: [PATCH B 04/10] OMAP3 PRCM: add DPLL1-5 powerdomains, clockdomains;
	mark clocks

Each DPLL exists in its own powerdomain (cf 34xx TRM figure 4-18) and
clockdomain; so, create powerdomain and clockdomain structures for them.
Mark each DPLL clock as belonging to their respective DPLL clockdomain.
cf. 34xx TRM Table 4-27 (among other references).

linux-omap source commits are acdb615850b9b4f7d1ab68133a16be8c8c0e7419 and
