ARM: OMAP2: Remove defines and resource init for OMAP24XX EAC
There is no anymore legacy driver for OMAP24XX Enhanced Audio Controller in linux-omap and it was newer in mainline so cleanup these unneeded defines and initialization code. Signed-off-by: Jarkko Nikula <jarkko.nikula@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
