Remove the write to GMAC_1US_TIC_COUNTER for two reasons:
1. during initialisation or reinitialisation of the DWMAC core, the
core is reset, which sets this register back to its default value.
Writing it prior to stmmac_dvr_probe() has no effect.
2. Since commit 8efbdbfa99 ("net: stmmac: Initialize
MAC_ONEUS_TIC_COUNTER register"), GMAC4/5 core code will set
this register based on the rate of plat->stmmac_clk. This clock
is created by the same code which initialises plat->eee_usecs_rate,
which is also created to run at this same rate. Since Marek's
commit, this will set this register appropriately using the
rate of this clock.
Therefore, dwmac-intel.c writing GMAC_1US_TIC_COUNTER serves no
useful purpose and can be removed.

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.
