omap4_cminst_wait_module_ready() checks if register offset is NULL.

int omap4_cminst_wait_module_ready(u8 part, u16 inst, s16 cdoffs,
				   u16 clkctrl_offs)
{
	int i = 0;

	if (!clkctrl_offs)
		return 0;

In case of AM33xx, CLKCTRL register offset for different clock domains
are not uniformly placed. An example of this would be the RTC clock
domain with CLKCTRL offset at 0x00.
In such cases the module ready check is skipped which leads to a data
abort during boot-up when RTC registers is accessed.

Since the actual base address is verified in
omap4_cminst_read_inst_reg(), this check here is not required at all
and hence can be removed.
