ARM: MAINTAINERS: drop empty entries for removed boards

Drop empty and redundant maintainer entries for boards which were
removed to fix `scripts/get_maintainer.pl --self-test=sections` errors
like:

  ./MAINTAINERS:2021: warning: section without file pattern	ARM/CIRRUS LOGIC EDB9315A MACHINE SUPPORT

[arnd: only remove the obviously stale ones for now]
