OMAP: PM: Fix build when CONFIG_PM_DEBUG isn't set

Since 6cdee91257bee23a46dc869ca62469b67cba2c7e the references to
enable_off_mode and sleep_while_idle can't be resolved when CONFIG_PM_DEBUG
isn't set:
arch/arm/mach-omap2/built-in.o: In function `omap_uart_restore_context':
arch/arm/mach-omap2/serial.c:253: undefined reference to `enable_off_mode'
arch/arm/mach-omap2/built-in.o: In function `omap3_can_sleep':
arch/arm/mach-omap2/pm34xx.c:479: undefined reference to `sleep_while_idle'

Simply #define these in pm.h just like omap2_pm_debug.
