ARM: OMAP4+: hwmod: Add hwmod flag for HWMOD_OMAP4_ZERO_CLKCTRL_OFFSET
Nearly all modules on OMAP4 and newer platforms have clkctrl offsets that are non-zero except for the RTC on am335x. Because we rely on a clkctrl_offset of zero to indicate no clkctrl_offset being present, lets add a HWMOD_OMAP4_ZERO_CLKCTRL_OFFSET flag to use to indicate hwmods that have a valid clkctrl_offset of 0.
