Stephan Gerhold 4a1f08cb58 arm64: dts: qcom: msm8916: Use higher I2C drive-strength only on DB410c 
Commit c240f29e75 ("arm64: dts: set the default i2c pin drive strength to 16mA")
changed the default drive-strength for I2C pins in msm8916-pins.dtsi
to the maximum possible (16 mA).

While this makes sense for apq8016-sbc (DB410c) where you can connect
an arbitrary amount of I2C devices with level shifters etc, there is
no need to use a higher drive strength for other MSM8916 devices.
The minimum drive strength (2 mA) seems to be totally sufficient
to have everything work there.

With the short pinctrl nodes introduced earlier we can easily override
the drive-strength only for apq8016-sbc now. Use that and change
the default back to 2 mA.

i2c1_default/i2c5_default are already using 2 mA because they were
added separately later and are not used in apq8016-sbc.

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.
