Do not enable TX_PIN_CFG_LNA_PE_A* bits for 2.4GHz band and
vice versa TX_PIN_CFG_LNA_PE_G* bits for 5GHz.

The TX_PIN_CFG_RFRX_EN bit was not set on other devices than MT7620,
restore old behavaviour since setting this bit maight not be
correct for older devices.

rt2800_config_channel_rf53xx() which is not called for RT6352 devices.

We do not need separate lines for calculating register values.
Also add comment that value is different than in vendor driver.
