MAINTAINERS: Add myself into x86 platform driver maintainers

Hans has been asking for another person to help as the maintainer of
the x86 platform driver because Mark has not been able to find time to
do that. I got asked for the task and have been reviewing the relevant
patches for a while now but lets make it more official by adding the
MAINTAINERS entries.
