hw/arm/aspeed: Split YosemiteV2 machine into a separate source file for maintainability

This commit moves the YosemiteV2 BMC machine implementation from
aspeed.c into a new standalone file aspeed_ast2500_yosemitev2.c.

To support splitting YosemiteV2 into a dedicated source file,
a new YOSEMITEV2_BMC_HW_STRAP1 macro is added as a copy of
AST2500_EVB_HW_STRAP1.

The refactor is part of an ongoing effort to modularize Aspeed
machine definitions by separating each board into its own source
file. This improves code readability, maintainability, and simplifies
future platform-specific changes.

Key updates include:

- Moved yosemitev2_bmc_i2c_init() and its FRU data into a new file.
- Removed aspeed_machine_yosemitev2_class_init() and type registration
from aspeed.c.
- Removed YosemiteV2 FRUID data and declarations from
aspeed_eeprom.c and aspeed_eeprom.h.
- Added aspeed_ast2500_yosemitev2.c to the build system
(meson.build).

No functional changes.
