bus: ti-sysc: Implement quirk handling for CLKDM_NOAUTO
For dra7 dcan and dwc3 instances we need to block clockdomain autoidle. Let's do this with CLKDM_NOAUTO quirk flag and enable it for dcan and dwc3. Cc: Keerthy <j-keerthy@ti.com> Cc: Roger Quadros <rogerq@ti.com> Cc: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
