Reland "drivers/intel/dptf: Add multiple fan support under dptf"
This reverts commit 4dba71fd25c91a9e610287c61238a8fe24452e4e.
Add multiple fan support for dptf policies.
This also fixes the Google Meet resolution drop issue as per
b:246535768 comment#12. When system starts Google Meet video call,
it uses the hardware accelerated encoder as expected. But, as soon as
another system connects to the call, an immediate fallback is observed
from hardware to software encoder. Due to this, Google Meet resolution
dropped from 720p to 180p. This issue is observed on Alder Lake-N SoC
based fanless platforms. This same issue was not seen on fan based
systems. With the fix in dptf driver where fan configures appropriate
setting for only fan participant, not for other device participants,
able to see consistent 720p resolution.
BUG=b:246535768,b:235254828
BRANCH=None
TEST=Built and tested on Alder Lake-P Redrix system for two fans
support and on Alder Lake-N fanless systems. With this code change
Google Meet resolution drop not observed.
