ARM: OMAP4: PM: Make OMAP3 Clock-domain framework compatible for OMAP4.

Browse Source 
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.
