clk: meson: axg-audio: add g12a support

Browse Source 
The g12a audio clock controller is largely similar to the existing axg
controller, with the addition of the spdif output B and TDM pad clocks.

This commit extends the existing axg audio clock controller driver
to work with multiple compatibles and add the g12a specific clocks
