Bindings for Samsung S2M and S5M family PMICs are in mess. They are
spread over different files and subdirectories in a non-consistent way.
The devices and respective drivers for them share a lot in common so
everything could be organized in a more readable way.

Reorganize the S2MPS11/13/14/15 Device Tree bindings to match the
drivers for this family of devices:
 - move mfd/s2mps11.txt to mfd/samsung,sec-core.txt for the main MFD
   driver (common for entire family),
 - split clock block to clock/samsung,s2mps11.txt,
 - split regulator block to regulator/samsung,s2mps11.txt.

As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.

This also start to propagate the negative error code from the
smbus call if there is one, as the last commit of this series
will make the gpiolib core deal with that properly.

Pull libnvdimm updates from Dan Williams:
 "The bulk of this has appeared in -next and independently received a
  build success notification from the kbuild robot.  The 'for-4.5/block-
  dax' topic branch was rebased over the weekend to drop the "block
  device end-of-life" rework that Al would like to see re-implemented
  with a notifier, and to address bug reports against the badblocks
  integration.

  There is pending feedback against "libnvdimm: Add a poison list and
  export badblocks" received last week.  Linda identified some localized
  fixups that we will handle incrementally.

  Summary:

   - Media error handling: The 'badblocks' implementation that
     originated in md-raid is up-levelled to a generic capability of a
     block device.  This initial implementation is limited to being
     consulted in the pmem block-i/o path.  Later, 'badblocks' will be
     consulted when creating dax mappings.

   - Raw block device dax: For virtualization and other cases that want
     large contiguous mappings of persistent memory, add the capability
     to dax-mmap a block device directly.

   - Increased /dev/mem restrictions: Add an option to treat all
     io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access
     while a driver is actively using an address range.  This behavior
     is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be
     overridden by the existing "iomem=relaxed" kernel command line
     option.

   - Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
     block device shutdown crash fix, and other small libnvdimm fixes"

Currently in bq27541 driver, the average power register address is
incorrectly set to 0x76, which would result in an error:
bq27xxx-battery 2-0055: error reading average power register  10: -11
According to the bq27541 datasheet, fix this problem by setting
the average power register address to 0x24.
