Subject: [PATCH] PM / s2idle: Export s2idle_set_ops

As suspend_set_ops is exported in commit a5e4fd8783a2
("PM / Suspend: Export suspend_set_ops, suspend_valid_only_mem"),
exporting s2idle_set_ops to make kernel module setup s2idle ops too.

In this way, kernel module can hook platform suspend
functions regardless of Suspend-to-Ram(S2R) or
Suspend-to-Idle(S2I)
