Erwan Le Ray c8a9d04394 serial: stm32: fix word length configuration
STM32 supports either:
- 8 and 9 bits word length (including parity bit) for stm32f4 compatible
  devices
- 7, 8 and 9 bits word length (including parity bit) for stm32f7 and
  stm32h7 compatible devices.

As a consequence STM32 supports the following termios configurations:
- CS7 with parity bit, and CS8 (with or without parity bit) for stm32f4
  compatible devices.
- CS6 with parity bit, CS7 and CS8 (with or without parity bit) for
  stm32f7 and stm32h7 compatible devices.

This patch is fixing word length by configuring correctly the SoC with
supported configurations.

README

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.
