[PATCH V5 4/8] perf/x86/intel: Reorganize attrs and is_visible

From: kan . liang
Date: Wed Oct 25 2023 - 16:16:40 EST


From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>

Some attrs and is_visible implementations are rather far away from one
another which makes the whole thing hard to interpret.

There are only two attribute groups which have both .attrs and
.is_visible, group_default and group_caps_lbr. Move them together.

No functional changes.
