This commit moves the Romulus BMC machine implementation out of aspeed.c into a new standalone file aspeed_ast2500_romulus.c.
The refactor continues the modularization of Aspeed platform definitions, separating each board into its own C source file to improve maintainability, readability, and reduce code clutter in aspeed.c. Key updates include: - Moved ROMULUS_BMC_HW_STRAP1 definition to the new file. - Moved romulus_bmc_i2c_init() and related I²C device setup. - Moved aspeed_machine_romulus_class_init() and type registration to aspeed_ast2500_romulus.c. - Added the new file to the build system (meson.build). - Removed all Romulus-specific code from aspeed.c. No functional changes.
