OMAP3: PM: CPUidle: fix init sequencing 

Previously omap3_idle_init() was called in device_init, while
omap_pm_init() is called at late_initcall. This causes the cpu idle
driver to call omap_sram_idle before it is properly initialized. This
patch fixes the issue by moving omap3_idle_init into omap3_pm_init.
