doxygen: add prefix for groups

Add "group_" prefix to doxygen group names. This makes
it easier to grep with group name later.

This patch only modifies the groups defined in the pathes
of INPUT of documentation/Doxyfile:

INPUT = . \
        ../src \
        ../include \
        ../components/finsh \
        ../components/drivers/include/drivers \
        ../components/drivers/clk \
        ../components/dfs/dfs_v2/src \
        ../components/dfs/dfs_v2/include

Other groups are not touched.
