There are still quite a few cases where a device might want
to get to a different node of the device-tree, obtain the
resources and map them.
We have of_iomap() and of_io_request_and_map() but they both
have shortcomings, such as not returning the size of the
resource found (which can be useful) and not being "managed".
This adds a devm_of_iomap() that provides all of these and
should probably replace uses of the above in most drivers.

commit 532fc475a103cc9968827c1cba851fe2b3100aba)
Fix pin conflicts when gpio4c7 is used for hdmi_cec and edp_hpd. CEC is an
optional function for HDMI. Thus the hdmi_cec pin should be specified
in the board .dts.
Without this patch we see below pin conflict when both hdmi and edp enabled.

(cherry picked from commit 6b22b3d161)
commit 5012284700 upstream.
Commit 8844618d8a: "ext4: only look at the bg_flags field if it is
valid" will complain if block group zero does not have the
EXT4_BG_INODE_ZEROED flag set. Unfortunately, this is not correct,
since a freshly created file system has this flag cleared. It gets
almost immediately after the file system is mounted read-write --- but
the following somewhat unlikely sequence will end up triggering a
false positive report of a corrupted file system:
mkfs.ext4 /dev/vdc
mount -o ro /dev/vdc /vdc
mount -o remount,rw /dev/vdc
Instead, when initializing the inode table for block group zero, test
to make sure that itable_unused count is not too large, since that is
the case that will result in some or all of the reserved inodes
getting cleared.
This fixes the failures reported by Eric Whiteney when running
generic/230 and generic/231 in the the nojournal test case.
