[PATCH v4 03/30] hw/arm/aspeed: Export and rename create_pca9552() for reuse

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

The helper function create_pca9552() has been renamed to
aspeed_create_pca9552() and made non-static for reuse by other Aspeed
machine source files. A corresponding prototype is now declared in
aspeed.h.

This allows multiple Aspeed platforms to share PCA9552 I2C LED controller
initialization logic, improving code reuse and reducing duplication.

No functional changes.
