ARM: OMAP2+: first hwmod fix for v4.6-rc

Fix a longstanding bug in the hwmod code that could cause
hardware SYSCONFIG register values to not match the kernel's
idea of what they should be, and that could result in lower
performance during IP block idle entry.

Basic build, boot, and PM test logs are available here:

ocfs2: fix a tiny race that leads file system read-only

when o2hb detect a node down, it first set the dead node to recovery map
and create ocfs2rec which will replay journal for dead node. o2hb
thread then call dlm_do_local_recovery_cleanup() to delete the lock for
dead node. After the lock of dead node is gone, locks for other nodes
can be granted and may modify the meta data without replaying journal of
the dead node. The detail is described as follows.

N1 N2 N3(master)
modify the extent tree of
inode, and commit
dirty metadata to journal,
then goes down.
o2hb thread detects
N1 goes down, set
recovery map and
delete the lock of N1.

dlm_thread flush ast
for the lock of N2.
do not detect the death
of N1, so recovery map is
empty.

read inode from disk
without replaying
the journal of N1 and
modify the extent tree
of the inode that N1
had modified.
ocfs2rec recover the
journal of N1.
The modification of N2
is lost.

The modification of N1 and N2 are not serial, and it will lead to
read-only file system. We can set recovery_waiting flag to the lock
resource after delete the lock for dead node to prevent other node from
getting the lock before dlm recovery. After dlm recovery, the recovery
map on N2 is not empty, ocfs2_inode_lock_full_nested() will wait for ocfs2
recovery.

BUG if the lockres is $RECOVERY

This series of patches add a new message to keep the order of set and
clear. Other nodes can purge the lock resource only after the refmap bit
on master is cleared.

This patch is to add DEREF_DONE message and corresponding handler. Node
can purge the lock resource after receiving this message. As a new
message is added, so increase the minor number of dlm protocol version.

Refer to cluster/tcp.h, NET_MAX_PAYLOAD_BYTES is a typo for

Since currently DLM_MIG_LOCKRES_RESERVED is not actually used, it won't
cause any problem. But we'd better correct it for further use.
