OMAP: clockdomain code/data: remove omap_chip bitmask from struct clockdomain
At Tony's request, remove the omap_chip bitmasks from the clockdomain and clockdomain dependency definitions. Instead, initialize clockdomains based on one or more lists that are applicable to a particular SoC family, variant, and silicon revision. Tony Lindgren <tony@atomide.com> found a bug in a previous version of this patch - thanks Tony. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Tony Lindgren <tony@atomide.com>
