This refactor continues the modularization effort of the Aspeed platform machine definitions, separating each board=E2=80=99s initialization logic i= nto its own dedicated source file. It improves code maintainability, readability, and reduces clutter in aspeed.c, simplifying future platform extensions. Key updates include: - Moved AST2600_EVB_HW_STRAP1 and AST2600_EVB_HW_STRAP2 macro definitions into the new aspeed_ast2600_evb.c file. - Moved ast2600_evb_i2c_init() and related device initialization code into the new aspeed_ast2600_evb.c file. - Moved aspeed_machine_ast2600_evb_class_init() and type registration logic out of aspeed.c. - Added aspeed_ast2600_evb.c to the Meson build system (meson.build). - Cleaned up all AST2600 EVB-specific code and macros from aspeed.c. No functional changes.
