[PATCH 6.6 222/299] bus: imx-weim: fix valid range check

[ Upstream commit 7bca405c986075c99b9f729d3587b5c45db39d01 ]

When the range parsing was open-coded the number of u32 entries to
parse had to be a multiple of 4 and the driver checks this. With
the range parsing converted to the range parser the counting changes
from individual u32 entries to a complete range, so the check must
not reject counts not divisible by 4.

Fixes: 2a88e4792c6d ("bus: imx-weim: Remove open coded "ranges" parsing")
