[PATCH 07/07] pm: remove platform device suspend_late()/resume_early()

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm@igel.co.jp>

This patch removes the legacy platform driver power management
callbacks ->suspend_late() and ->resume_early() since all in-tree
users have been migrated to dev_pm_ops.

Signed-off-by: Magnus Damm <damm@igel.co.jp>

 Untested but compiles fine.
