Proceed with the consolidation of TX/RX path config by carving out some
TX configuration out into a separate function. For now, this only
affects TX amplifier config. But it already slims down other polluted
call sites and brings some structure into the TX/RX path config.
While at it, already provide a similar function for RX configuration.
This does nothing yet but should be filled with RX path config later.
