MAINTAINERS: Add Mark Gross and Hans de Goede as x86 platform drivers maintainers

maintain the x86 platform drivers, dropping their status to:
"Odd Fixes".

Mark Gross and Hans de Goede will take over maintainership of
the x86 platform drivers. Replace Darren and Andy's entries with
theirs and change the status to "Maintained".
