hw/arm: Introduce ASPEED AST2700 A1 full core machine

hw/arm: Introduce ASPEED AST2700 A1 full core machine

- Added new machine type `ast2700fc` with full core support.
- Defined `Ast2700FCState` structure for the new machine type.
- Implemented initialization functions for CA35, SSP, and TSP components.
- Updated `ast2700fc_types` to include the new machine type.
- Set machine class properties for `ast2700fc`.

Test Step:
- Download ast2700-default-obmc.tar.gz from AspeedTech-BMC OpenBmc
  release page.
- Run the following QEMU command:

  ```
  IMGDIR=~/path/to/image
  UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)

  ./qemu-system-aarch64 -machine ast2700fc \
  -device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \
  -device loader,force-raw=on,addr=$((0x400000000 + ${UBOOT_SIZE})),file=${IMGDIR}/u-boot.dtb \
  -device loader,force-raw=on,addr=0x430000000,file=${IMGDIR}/bl31.bin \
  -device loader,force-raw=on,addr=0x430080000,file=${IMGDIR}/tee-raw.bin \
  -device loader,cpu-num=0,addr=0x430000000 \
  -device loader,cpu-num=1,addr=0x430000000 \
  -device loader,cpu-num=2,addr=0x430000000 \
  -device loader,cpu-num=3,addr=0x430000000 \
  -device loader,file=${IMGDIR}/ast2700-ssp.elf,cpu-num=4 \
  -device loader,file=${IMGDIR}/ast2700-tsp.elf,cpu-num=5 \
  -drive file=${IMGDIR}/image-bmc,if=mtd,format=raw \
  -serial pty -serial pty -serial pty \
  -snapshot \
  -S -nographic
  ```

- After starting QEMU, serial devices will be redirected:

  char device redirected to /dev/pts/51 (label serial0)
  char device redirected to /dev/pts/52 (label serial1)
  char device redirected to /dev/pts/53 (label serial2)

- serial0 is the console for the four Cortex-A35 primary processors,
  serial1 and serial2 are the consoles for the two Cortex-M4 coprocessors.

- Connect to the consoles using a terminal emulator.
