MAINTAINERS: Simplify entries for Arm Vexpress platform and related drivers

Currently the entries have regexs but in absolute paths. The "N:" entries
can deal with all files and directories irrespective of the depth/path
matching the regex patterns.

Simplifies the entry by making using "N:" and dropping "F:" with absolute
paths.
