[PATCH] MAINTAINERS: Add mpam.rst to the MPAM DRIVER entry

[Fuad Tabba]

Documentation/arch/arm64/mpam.rst is not listed under MPAM DRIVER, so
get_maintainer.pl names neither MPAM maintainer on a patch to it.

Notes:
    Found this while putting together the recipient list for [1]:
    get_maintainer.pl names neither MPAM maintainer on a patch to mpam.rst.
    
    arch/arm64/kernel/mpam.c, arch/arm64/include/asm/mpam.h and
    drivers/acpi/arm64/mpam.c aren't in this entry either, but that
    didn't look as clear cut, so I've left them out. Happy to respin
    with them added.
