ARM: OMAP2+: Remove unused legacy code for opp
We are now booting all mach-omap2 in device tree only mode. Any code that is only called in legacy boot mode where of_have_populated_dt() is not set is safe to remove now. Note that the volt_data is still being used. Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk> Signed-off-by: Tony Lindgren <tony@atomide.com>
