hw/sd/omap_mmc: Do a minimal conversion to QDev

Browse source 
Do a minimal conversion of the omap_mmc device model to QDev.

In this commit we do the bare minimum to produce a working device:
 * add the SysBusDevice parent_obj and the usual type boilerplate
 * omap_mmc_init() now returns a DeviceState*
 * reset is handled by sysbus reset, so the SoC reset function
   doesn't need to call omap_mmc_reset() any more
 * code that should obviously be in init/realize is moved there
   from omap_mmc_init()

We leave various pieces of cleanup to later commits:
 * rationalizing 'struct omap_mmc_s *' to 'OMAPMMCState *'
 * using gpio lines rather than having omap_mmc_init() directly
   set s->irq, s->dma
 * switching away from the legacy SD API and instead having
   the SD card plugged into a bus
