Sometimes command can't be completed within the time give
in eSDHC_SYSCTL[DTOCV]. So just give the max value 0x14 to
avoid this issue.

Please don't line up the continuation lines of the if-condition with
the if-body.
Please check variant SoCs as well. If the bug exists on p4080, then it
exists on p4040. Likewise with p5040/p5021, and p5020/p5010.
Is it present on all revisions of these SoCs? How about p3041, which
is usually pretty similar to p5020? p2040/p2041? Is there an erratum
number for this problem?
