Currently, clock configuration is spread throughout the driver and partially duplicated for the STM32MP1 and STM32 MCU variants. This makes it difficult to keep track of which clocks need to be enabled or disabled in various scenarios. This patch adds symmetric stm32_dwmac_clk_enable/disable() functions that handle all clock configuration, including quirks required while suspending or resuming. syscfg_clk and clk_eth_ck are not present on STM32 MCUs, but it is fine to try to configure them anyway since NULL clocks are ignored.

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.
