Add reset assertion/deassertion for Aspeed MDIO. There are 4 MDIO controllers embedded in Aspeed AST2600 SOC and share one reset control register SCU50[3]. To work with old DT blobs which don't have the reset property, devm_reset_control_get_optional_shared is used in this change.

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.
