ARM: OMAP3/OMAP4: PRM: add prm_features flags and add IO wakeup under it
prm_features flag will contain SoC specific feature enabler flags. Initially IO wakeup is added under this. Helps to get rid of runtime cpu_is_X checks. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
