dt-bindings: arm: amlogic: introduce specific compatibles for S4 family

The Amlogic S4 SoC family includes multiple variants, such as the S805X2
and S905Y4. Currently, the bindings only define the generic "amlogic,s4"
compatible.

This patch introduces specific compatibles "amlogic,s805x2" and
"amlogic,s905y4" to properly differentiate these SoCs while keeping
"amlogic,s4" as the family fallback.

This allows for more precise hardware description and future-proofing
if SoC-specific quirks arise.
