and adjusts the Makefile/Kconfig entries in a way that it's possible
to compile i.MX5 together with i.MX3/6.

Any soc that needs a customized idle implementation other than
cpu_do_idle() can set up this hook in soc specific call.

Implement code for MX51 that allows the SoC to enter WFI when
arch_idle is called.

This patch is also necessary for correctly suspending the system.
