mainlining shenanigans

Hello!
This series adds support for the Embedded Controller which is found on
Acer Iconia Tab A500 (Android tablet device).
The Embedded Controller is ENE KB930 and it's running firmware customized
for the A500. The firmware interface may be reused by some other sibling
Acer tablets, although none of those tablets are supported in upstream yet.
Please review and apply, thanks in advance!
Changelog:
v2: - Factored out KB930 device-tree binding into a separate file, like it
was suggested by Lubomir Rintel.
- Switched to use regmap API like it was suggested by Lubomir Rintel.
- Added patch "regmap: Use flexible sleep" which allows not to hog
CPU while LED is switching state.
- Corrected MODULE_LICENSE to use "GPL" in all patches.
- Corrected MFD driver Kconfig entry like it was suggested by
Lubomir Rintel, it now depends on I2C.
- Switched to use I2C probe_new() in the MFD driver.
- Renamed the global pm_off variable, like it was suggested by
Lubomir Rintel and Lee Jones.
- Dropped serial number from the battery driver because I realized
that it's not a battery serial, but a device serial.
- Battery driver now uses dev_err_probe(), like it was suggested by
Sebastian Reichel.
- Dropped legacy LED_ON usage from the LED driver and renamed the
LEDs, like it was suggested by Pavel Machek. I also checked whether
LED-name customization via device-tree could be needed by other
potentially compatible devices and it shouldn't be needed, anyways it
won't be difficult to extend the code even if I'm wrong.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
