[PATCH v3 04/30] hw/arm/aspeed: Rename and export create_pca9554() as aspeed_create_pca9554()

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

The helper function create_pca9554() has been renamed to
aspeed_create_pca9554() and made globally available.

Previously, the function was declared static inside aspeed.c, restricting
its visibility to that file. As more Aspeed machine implementations
require PCA9554 I²C expander setup, it makes sense to rename it with the
aspeed_ prefix and export its declaration in aspeed.h for shared use.

No functional changes.
