The power amplifier for the headphone output is called "the PA" and "the
headphone amplifier" in Allwinner's documentation for the A10 and A20.
sun4i-codec calls it "PA" in some places and "Pre-Amplifier" (which
isn't really accurate) in others, leading to user-visible controls with
different names
