Add CFM Limit interface
Add CFM limit interface to describe the upper CFM limit for a system. This can be used with a CFM algorithm to calculate the maximum allowed fan speed for a system. A common usage of the CFM limit is to set a hard acoustic limit for a system. Change-Id: I3e7f37fcf48a2c958c8596a33a631ca327002df9 Signed-off-by: James Feist <james.feist@linux.intel.com>
