bus: ti-sysc: Detect omap4 type timers for quirk
Starting with omap4 some timers have different sysc registers (type2) compared to the omap2 timers (type1). We need to detect these to enable the quirk for SYSC_QUIRK_LEGACY_IDLE, otherwise these won't be idling properly. Siganed-off-by: Tony Lindgren <tony@atomide.com>
