qcacmn: Add support to retrieve SAR power limits
Recently change "qcacmn: Add SAR power limit configuration"
(Change-Id: I0a214a2af780e9dd8c381c4e9eaa7d8cab6ef853) added the
ability to dynamically configure Specific Absorption Rate (SAR) power
limits. Now add the ability to retrieve the current active power
limits.
