Dmitry Lebed e085b51c74 mmc: meson-gx: check for scatterlist size alignment in block mode
Enable SGDMA support for SD_IO_RW_EXTENDED and add proper check
for scatterlist size alignment in block mode.

According to documentation, in SDIO block mode meson-gx DMA could
only handle buffers with sizes that are multiples of SDIO block size.

Some SDIO drivers like brcmfmac use scatterlist API, but do not enforce
proper scatterlist buffer size alignemnt, this looks like a root cause
of non-working CMD53.

Some minor style fixes.

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.
