ARM: OMAP2xxx: hwmod data: add HDQ/1-wire hwmod

Add the HDQ1W hwmod for all OMAP2xxx devices. Assume that OMAP2xxx chips have the same HDQ idle handling bug as OMAP3: http://www.spinics.net/lists/linux-omap/msg63576.html and set the OCPIF_SWSUP_IDLE flag accordingly on the HDQ's OCP interface. Signed-off-by: Paul Walmsley <paul@pwsan.com>
