This is yet another simple but odd driver for the audio block of the g12a
and sm1 SoC families.
For TDMOUT's sclk to be properly inverted, bit 29 of
AUDIO_CLK_TDMOUT_x_CTRL should be the inverse of bit 28.
IOW bit28 == !bit29 at all times
This setting is automatically applied on axg and the manual setting was
added on g12a.

If the init callback is allowed to request resources, it needs a return
value to report the outcome of such a request.

Initially, the meson clock directory only hosted 2 controllers drivers,
for meson8 and gxbb. At the time, both used the same set of clock drivers
so managing the dependencies was not a big concern.
Since this ancient time, entropy did its job, controllers with different
requirement and specific clock drivers have been added. Unfortunately, we
did not do a great job at managing the dependencies between the
controllers and the different clock drivers. Some drivers, such as
clk-phase or vid-pll-div, are compiled even if they are useless on the
target (meson8). As we are adding new controllers, we need to be able to
pick a driver w/o pulling the whole thing.
The patch aims to clean things up by:
* providing a dedicated CONFIG_ for each clock drivers
* allowing clock drivers to be compiled as a modules, if possible
* stating explicitly which drivers are required by each controller.
