2.6 LNA and AFE Enable/Disable

If LNA or the entire AFE (LNA+LOG Detector) is not in use, then disable to save power. This can be done by pulling down the LNA_En and AFE_En pin to ground by shorting the jumper between PIN1 and PIN2 of J3 and J2, respectively. Keeping the pin floating or shorting PIN2 and PIN3 of these two jumpers keeps the two blocks enabled.
