Geert Uytterhoeven b928bf4d0d pinctrl: renesas: checker: Limit cfg reg enum checks to provided IDs 
[ Upstream commit 3803584a4e9b65bb5b013f862f55c5055aa86c25 ]

If the number of provided enum IDs in a variable width config register
description does not match the expected number, the checker uses the
expected number for validating the individual enum IDs.

However, this may cause out-of-bounds accesses on the array holding the
enum IDs, leading to bogus enum_id conflict warnings.  Worse, if the bug
is an incorrect bit field description (e.g. accidentally using "12"
instead of "-12" for a reserved field), thousands of warnings may be
printed, overflowing the kernel log buffer.

Fix this by limiting the enum ID check to the number of provided enum
IDs.
