[PATCH v3 0/3] Add imx cpuidle

[Robert Lee]

Add common imx cpuidle initialization functionality and add a i.MX5 and i.MX6Q
platform cpuidle implementation.

Based on v3.4-rc6 plus recently submitted device tree late_initcall patch:
 http://www.spinics.net/lists/arm-kernel/msg171620.html

v3 changes:
 * removed file introduced in v1 no longer needed after v2 [per Shawn Guo]
 * re-ordered added #includes in alphabetical order [per Shawn Guo]
 * Remove if(!drv) check to allow handling by stack trace [per Sascha Hauer]
 * Added missing return value in error meesage [per Shawn Guo]
 * fixed (void *) casting problem pointed out Sasha Hauer.  Used a different
   type of casting to properly give warning on improper casting:
   	arm_pm_idle = (void (*)(void))imx5_idle;
   Used this casting instead of adding a dummy caller function because
   adding the dummy function appears to unnecessarily introduce the following
   additional operations:
	static void imx5_pm_idle(void)
	{
	  a0:	e1a0c00d 	mov	ip, sp
	  a4:	e92dd800 	push	{fp, ip, lr, pc}
	  a8:	e24cb004 	sub	fp, ip, #4
		imx5_idle();
	  ac:	ebffffd3 	bl	0 <imx5_idle>
	}
	  b0:	e89da800 	ldm	sp, {fp, sp, pc}

v2 changes:
 * Removed some unnecessary  spaces [per Jess Juhl]
 * Added return value for an error message [per Sascha Hauer]
 * Reworked init scheme to use device tree late_initcall [per Sascha and Shawn]
 * Moved imx6q and imx5 cpuidle functionality to existing files.
