[PATCH 13/16] bus: ti-sysc: Detect omap4 type timers for quirk

[Tony Lindgren]

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.
