[PATCH v2 2/3] staging: rtl8723bs: access TxPowerByRateBase2_4G directly

[Leonardo Martins Martins <dev.lmmrtns@gmail.com>]

In phy_tx_power_limit_to_index(), pwr_base is acquired from
TxPowerByRateBase2_4G using rs, which itself is an iterator between
0 and 2, but it's accessed by using an if-else chain that then passes
the equivalent enum constant to PHY_GetTxPowerByRateBase(), which
checks RfPath against RF_PATH_MAX (which is already done by the loop),
then uses a switch-case statement on the enum to access
TxPowerByRateBase2_4G with the original value of rs.

Remove the redundant if-else, the call to PHY_GetTxPowerByRateBase() and
access it directly. Also remove PHY_GetTxPowerByRateBase() since those
were its only usages.
