well, the thought process here was that since the audio block control driver (i.e.: clk-imx8mp-audiomix.c)
is compiled as built-in (CONFIG_CLK_IMX8MP=y) we'd want to have the bridge as built-in too so as to not
defer the probe of the clock provider and its consumers (in case there's any compiled as built-in).

however, the bridge driver could have just as well been compiled as a module so any of the two approaches
is fine with me.
