Add SAR implemention that allows driver to set SAR power from
three different sources:
1. From vendor command
2. From static SAR configuration
3. From dynamic SAR
SAR sources will provide driver a list of target power in dBm
which should be translated into power indexes. Then driver
will just treat those indexes as another power limit to force
the power output being lower then SAR restriction.
For either vendor command, static or dynamic SAR, driver stores
the values in tx_pwr_sar_{2,5}g[regd][path][rs][ch]. Whenever
the channel is changed or a new SAR table is applied, driver
will configure the power indexes.
To check if SAR power is configured properly, append a column
to debugfs "tx_pwr_tbl". But for dynamic SAR, the profile ID
may change, so add a new debugfs "sar" to display SAR power.
