Amlogic A9 SoCs integrate the Silvaco I3C IP with two controller
instances:

- amlogic,a9-i3c for the EE domain, which takes two clocks,
"pclk" and "fast_clk" like the NXP variants;

- amlogic,a9-ao-i3c for the Always-On (AO) domain, which exposes
only "pclk": its bus clock is generated by an internal divider
located in the controller's own register space.

Allow both compatibles with the "silvaco,i3c-master-v1" fallback and
enforce the per-variant clock counts.

This we see in the diff, but we do not see WHY.

i will add a description of the I3C peripheral integratation detail at

hardware-level.


Best regards,
Krzysztof
