[PATCH V4 5/6] ARM: OMAP2+: AM33XX: add lateinit hook for calling pm late init

[Nishanth Menon <nm@ti.com>]

Call OMAP2+ generic lateinit hook from AM specific late init hook.
This allows the generic late initializations such as cpufreq hooks
to be active.

Introduced as a result of alignment in http://marc.info/?t=136450773400004&r=1&w=2
previous versions do not use this approach.
