This refactor continues the modularization effort for Aspeed platform suppo= rt, placing each board=E2=80=99s logic in its own dedicated source file. It imp= roves maintainability, readability, and simplifies future development for new platforms without cluttering aspeed.c. Key updates include: - Moved QCOM_DC_SCM_V1_BMC_HW_STRAP1 and QCOM_DC_SCM_V1_BMC_HW_STRAP2 macro into the new file aspeed_ast2600_qcom-dc-scm-v1.c. - Moved qcom_dc_scm_bmc_i2c_init() and aspeed_machine_qcom_dc_scm_v1_class_= init() into the new file aspeed_ast2600_qcom-dc-scm-v1.c. - Moved "qcom-dc-scm-v1-bmc" machine type registration from aspeed.c to the= new file. - Updated hw/arm/meson.build to include aspeed_ast2600_qcom-dc-scm-v1.c. - Cleaned up all QCOM DC-SCM V1-specific code from aspeed.c. No functional changes.
