feature-support: reset M3/M4 support lists (#257)
I marked all the M3/M4 features as 'TBA', except those M3 features where someone is actively working on them, which are now 'WIP'. Signed-off-by: Alyssa Milburn <amilburn@zall.org>

### cpuidle situation
113-
Some power management functionality on ARM machines is controlled via the PSCI interface. The
114-
kernel has a specific way of talking to PSCI that is not compatible with Apple Silicon, and a
115-
discussion is required with upstream maintainers in order to figure out the best way forward. Given
116-
that this discussion has failed to materialise for two years, the decision has been
117-
made to hack together a driver that directly calls WFI/WFE instructions in order to bring
118-
this functionality to Asahi Linux. This greatly improves the UX on laptops when coupled with
119-
energy-aware scheduling, as it resolves the issue of the machines running warm to the touch
120-
and significantly improves battery life. This can never be upstreamed, however the hope is
121-
that this hacked together driver becomes unnecessary at some point in the near future.
