asmc(4): pull 32-bit support for the driver
The asmc(4) driver should work for 32-bit Intel-based Macs, in theory, if
the model details were added to the detection list. That being said,
32-bit Intel Macs were only released and available to the general public
for 8 months [1], so the value in maintaining i386 support in the driver is
reduced due to limited hardware access.
Remove 32-bit support for the driver officially to make it clear its use is
not supported.
This should fix building `NOTES.i386` by proxy as well.
Relnotes: yes
MFC after: 2 weeks
Fixes: f224591746b ("Add ASMC_DEBUG make option")
Fixes: 8342d9f7b5f ("asmc(4): Stop building it on i386, as...")
