Jamin Lin 21dc5fa31b hw/arm/aspeed: Split FBY35 BMC machine into a separate source file for maintainability 
This commit moves the Facebook fby35 BMC machine implementation out of
aspeed.c into a new standalone file aspeed_ast2600_fby35.c.

This refactor continues the modularization effort for Aspeed platform support,
placing each board’s logic in its own dedicated source file.
It improves maintainability, readability, and simplifies future development for
new platforms without cluttering aspeed.c.

Key updates include:
- Moved fby35_i2c_init() and fby35_reset() to the new file.
- Moved aspeed_machine_fby35_class_init() and machine registration to the new file.
- Removed fby35 FRU data (fby35_nic_fruid, fby35_bb_fruid, fby35_bmc_fruid) and their size definitions from aspeed_eeprom.[ch].
- Added aspeed_ast2600_fby35.c to the build system (meson.build).
- Cleaned up all fby35-specific code and declarations from aspeed.c and aspeed_eeprom.*.
- Introduced FBY35_BMC_RAM_SIZE macro based on FUJI_BMC_RAM_SIZE to remove
  inter-file dependency.

No functional changes.
