OMAP3: SDRC : Errata 1.176 Fix - Accesses to DDR stall in SDRC after a Warm-reset

Original patch: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg21030.html

Modified as in latona 2.6.35.
OMAP3: PM: make secure ram save size configurable

OMAP3 users of HS/EMU devices at times choose to use their
own PPA which could be configured to use different sized storage
area based on their security needs. Convert the hardcoded size
define to a more configurable form to map to these users. we introduce
the structure omap3_secure_copy_data to describe PPA specific behavior
we will further populate in follow on patches. secure_copy_data_set
is introduced to allow for board files to populate custom parameters
as desired.

OMAP3: PM: latona: disable INTC AUTOIDLE before saving secure RAM

Revert "latona: Skip Reprogramming of SDRC clock since dpll3 clock is not found."

This is not required, no errors are thrown.
