Cristian Ciocaltea f5b3f43364 i2c: owl: Clear NACK and BUS error bits
When the NACK and BUS error bits are set by the hardware, the driver is
responsible for clearing them by writing "1" into the corresponding
status registers.

Hence perform the necessary operations in owl_i2c_interrupt().

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.
