fw/layer1/tpu_window: Open and close RFFE tx_window at the right point of time 

So far, the PA-enable signal has been enabled way to early and
also has been disabled much too late.
We're now setting the RFFE to TX-mode after opening the ABB
window, and setting the RFFE to RX-mode again after TX. This
yields to an almost perfectly timed TX-window, just like with the
stock firmware of the phone.
