[PATCH 09/13] OMAP2+: PM: export suspend_set_ops to PM modules

[jean.pihet@newoldbits.com]

From: Jean Pihet <j-pihet@ti.com>

Export the suspend_set_ops API as omap_pm_suspend_set_ops in the pm
generic code, under CONFIG_SUSPEND.

Note -hack warning-: since the 'suspend_valid_only_mem' function is
not exported to modules, fill the 'valid' field value of
'struct platform_suspend_ops' in the common code.
