[PATCH v3 04/16] hw/arm/aspeed: Remove AspeedSoCClass dependency from aspeed_soc_cpu_type() API

[Jamin Lin via <qemu-devel@nongnu.org>]

Refactor the aspeed_soc_cpu_type() helper to remove its dependency on
AspeedSoCClass and make CPU type retrieval more generic.

The function now takes valid_cpu_types as a const char * const *
parameter instead of requiring a full AspeedSoCClass instance.
All corresponding call sites in various Aspeed SoC initialization files
(aspeed_ast10x0.c, aspeed_ast2400.c, aspeed_ast2600.c,
aspeed_ast27x0.c, and related variants) are updated accordingly.

This change simplifies the API, eliminates unnecessary type coupling,
and improves code reusability across different SoC families.

No functional change.
