Instead of reimplementing the logic in mmc_regulator_set_vqmmc(), use the mmc code function directly. This also allows us to fix a related issue on STM32MP1, when a voltage switch of 1.8V is done for the eMMC, but the current level is already set to 1.8V. More precisely, in this scenario the call to the ->post_sig_volt_switch() hangs, indefinitely waiting for the voltage switch to complete. Fix this problem by checking if mmc_regulator_set_vqmmc() returned 1 and then skip invoking the callback.

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.
