Josua Mayer 84185573da mmc: sdhci-esdhc-imx: Update esdhc sysctl dtocv bitmask
NXP ESDHC supports setting data timeout using uSDHCx_SYS_CTRL register
DTOCV bits (bits 16-19).
Currently the driver accesses those bits by 32-bit write using
SDHCI_TIMEOUT_CONTROL (0x2E) defined in drivers/mmc/host/sdhci.h.
This is offset by two bytes relative to uSDHCx_SYS_CTRL (0x2C).
The driver also defines ESDHC_SYS_CTRL_DTOCV_MASK as first 4 bits, which
is correct relative to SDHCI_TIMEOUT_CONTROL but not relative to
uSDHCx_SYS_CTRL. The definition carrying control register in its name is
therefore inconsistent.

Update the bitmask definition for bits 16-19 to be correct relative to
control register base.
Update the esdhc_set_timeout function to set timeout value at control
register base, not timeout offset.

This solves a purely cosmetic problem.

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.
