OMAP2+: disable idle early in the suspend sequence
Some bad interaction between the idle and the suspend paths has been
identified: the idle code is called during the suspend enter and exit
sequences. This could cause corruption or lock-up of resources.
The solution is to move the calls to disable_hlt at the very beginning
of the suspend sequence (ex. in omap3_pm_begin instead of
omap3_pm_prepare), and the call to enable_hlt at the very end of
the suspend sequence (ex. in omap3_pm_end instead of omap3_pm_finish).
Tested with RET and OFF on Beagle and OMAP3EVM.
