rG36b399f55e3f: asmc: rename wol sysctl to auto_poweron

Summary

Older SMC firmware exposed AUPO as a Wake-on-LAN control. On updated
firmware, the key controls automatic power-on when AC power is restored
after a power loss; WoL is handled by the GBE controller instead.
Rename the sysctl to reflect the current semantics. No compatibility
alias is provided as the sysctl has not appeared in any release.

How do you handle the case of older firmware? Won't this driver still use this for wake on lan?

Older firmware still works fine with this change.

I tested this on an older firmware (circa 2011–2012) and didn’t hit any regression. I cant re-test it now though; the machine updated its SMC/firmware and there is no downgrade path.

This change is really about correctness.
AUPO means Auto UP (Or something similar), not Wake-on-LAN. The current WOL naming that i introduced is misleading.

please fix the hyphen and then this'll be fine to land, thanks!

3	The copyright line was not added for this specific change, I have been modifying this file over the past four months as part of broader apple SMC work. Since this particular diff is a small rename, I agree it does not warrant adding a copyright, and have removed it.
