Both manual and power on resets have a brief period where the chip will not be accessible immediately afterwards. Extend the time allowed for this from a minimum of 1mS to 2mS based on newer evaluation of the hardware and ensure this reset happens in all reset conditions. Whilst making the change also remove the redundant NULL checks in the reset functions as the GPIO functions already check for this.

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.
