x86, 386 removal: Remove CONFIG_CMPXCHG
All 486+ CPUs support CMPXCHG, so remove the fallback 386 support
code.
Furthermore, as the commit-message states, all 486+ CPUs support the
CMPXCHG instruction and thus even legacy DRM can run fine.

pca954x may be power lost during suspend, so after resume we also suffer
the issue fixed by commit cd823db8b1,
"pca954x power-on default is channel 0 connected. If multiple pca954x
muxes are connected to the same physical I2C bus, the parent bus will
see channel 0 devices behind both muxes by default."
What's more, when resume bootloader may also operate the mux, so the
the channel connected after that may not be the one driver thought.
We fix this problem by putting the mux to disconnected state and
clearing last_chan in the resume hook.

Some I2C devices are out of spec, such as the HDMI link of the Toshiba
19AV600 TV, and might not work properly with minimum values.
This patch adds a 10% margin on all the timings in both Normal and Fast modes.
