This commit exposes the function aspeed_machine_ast2600_class_emmc_init() as
a common API so that other AST2600-based machine implementations can reuse it
to enable the "boot-emmc" property.

Previously, this function was defined as a static helper within aspeed.c,
limiting its visibility to that file. By making it global and declaring it in
aspeed.h, other machine definition files (e.g., for specific AST2600 boards)
can now easily call this API to register eMMC boot configuration support.

No functional changes.
