MAINTAINERS: adjust file entry in INTEL MID PLATFORM

Commit 5f1cda5 ("platform/x86: intel_scu_wdt: Move intel_scu_wdt.h to
x86 subfolder") moves intel-mid_wdt.h in ./include/linux/platform_data into
the x86 subdirectory, but misses to adjust the INTEL MID PLATFORM section,
which is referring to this file.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Adjust the file entry to this header file movement.
