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

["Cédric Le Goater" <clg@redhat.com>]

From: Jamin Lin <jamin_lin@aspeedtech.com>

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.
