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

[Magnus Damm]

From: Magnus Damm <damm@opensource.se>

Hook in shmobile_init_late() on Lager. 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)

Hi Magnus,

it seems that this patch needs the following so that shmobile_init_late
is defined. I am dropping this patch for now.
