omap3:clock: check cpu_family before enabling clks for IVA & CAM

In case of AM3517 and AM3505 (which is OMAP3 varients), IVA2 and
ISP-CAMERA modules have been removed. So add check for cpu_family before
enabling clocks for these modules, else this impacts subsequent
power consumption and system suspend/resume functionality.
