ARM: OMAP2+: HDQ1W: use omap_device
Convert the old-style device registration code for HDQ1W to use
omap_device. This will allow the driver to be converted to use PM
runtime and to take advantage of the OMAP IP block management
infrastructure (hwmod, PM, etc.).
A side benefit of this conversion is that it also makes the HDQ device
available on OMAP2420. The previous code only enabled it on 2430 and
3430.
