ARM: OMAP4: PM: Make OMAP3 Clock-domain framework compatible for OMAP4.
Here the ".clkstctrl_reg" field is added to the clockdomain stucture as the module offsets for OMAP4 do not map one to one for powerdomains and clockdomains as it used to for OMAP3. Hence we need to use absolute addresses to access the control registers. Some of the clock domains have modules falling in the address space of PRM partition. Hence necessitating the use of absolute adresses.
