nvmem_cell_read_u32() may return -EPROBE_DEFER if NVMEM supplier has not
yet been probed. Future reprobe may succeed, so printing:
i.mx8mm_thermal 30260000.tmu: Failed to read OCOTP nvmem cell (-517).
to the log is confusing. Fix this by using dev_err_probe. This also
elevates the message from warning to error, which is more correct: The
log message is only ever printed in probe error path and probe aborts
afterwards, so it really warrants an error-level message.
Fixes: 4032916488 ("thermal/drivers/imx: Add support for loading calibration data from OCOTP")

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.
