[PATCH v2] ARM: shmobile: Use ->init_late() on Lager

[Magnus Damm]

From: Magnus Damm <damm at opensource.se>

Hook in shmobile_init_late() on Lager V2. This enables some PM
related things like CPUIdle and Suspend-to-RAM.

With this patch applied it is possible to use Suspend-to-RAM:
# echo enabled > /sys/class/tty/ttySC6/power/wakeup
# echo mem > /sys/power/state 
(wake by sending a character on the serial console)

Signed-off-by: Magnus Damm <damm at opensource.se>

 Changes since V1:
 - added missing include <mach/common.h> to DT reference code
