Add reset-line handling to the RZN1 MIIC driver and move reset configuration into the SoC/OF data. Introduce MIIC_MAX_NUM_RSTS (= 2), add storage for reset_control_bulk_data in struct miic and add reset_ids and reset_count fields to miic_of_data. When reset_ids are present in the OF data, the driver obtains the reset lines with devm_reset_control_bulk_get_exclusive(), deasserts them during probe and registers a devres action to assert them on remove or on error. This change is preparatory work to support the RZ/T2H SoC, which exposes two reset lines for the ETHSS IP. The driver remains backward compatible for platforms that do not provide reset lines.

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 reStructuredText 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.
