qcacld-3.0: Reduce high throughput detection level

Currently the API hdd_is_current_high_throughput considers any
throughput level higher(or equal) than PLD_BUS_WIDTH_HIGH as high
throughput level. Based on this level, driver decides to take up RX
wakelock and log certain stats(TDLS). This can have an impact on power
even in HT20 modes.

Reduce the high throughput detection level to PLD_BUS_WIDTH_MEDIUM. So
throughput >= 60Mbps is considered high by the API.
