ARM: OMAP4+: Make control module register structure generic
A seperate omap_sys_ctrl_regs structure is defined for
omap4 & 5. If there is any change in control module for
any of the ES versions, a new structure needs to be created.
In order to remove this dependency, making the register
structure generic for all the omap4+ boards.
