Default LP#526354: suspend/resume breaks sensors and fan V3

We have been tracking an issue where suspend/resume breaks temperature
sensors (which read 0 permenantly) and fans no longer turn on correctly.
Upstream has tracked that to needing multi-byte access to the EC.
Following this email is a patch which has been tested here to fix the
issue. The original patch here caused boot panics on most ThinkPad models
and at least some MacBooks. This is a second replacement version of this patch
which still fixes the Dell systems, and does not kill ThinkPads nor MacBooks.

Tested good here on both the original Dell and on a ThinkPad T30.
Awaiting other testing feedback from affected users.
