From: Tzu-En Huang <tehuang@xxxxxxxxxxx>
For power by rate table, 8822b needs to use bcd2bin() to parse the
table, while 8822c does not. Variable is_pwr_by_rate_dec is used to
identify whether we need to treat the value from the table as BCD code
or not.
And since the unit of tx power index diff is changed in 8822c, the index
is multiplied by a factor to get desired index value.
