aspeed: Refactor UART init for multi-SoC machines
This change moves the code that connects the SoC UART's to serial_hd's
to the machine.
It makes each UART a proper child member of the SoC, and then allows the
machine to selectively initialize the chardev for each UART with a
serial_hd.
This should preserve backwards compatibility, but also allow multi-SoC
boards to completely change the wiring of serial devices from the
command line to specific SoC UART's.
This also removes the uart-default property from the SoC, since the SoC
doesn't need to know what UART is the "default" on the machine anymore.
I tested this using the images and commands from the previous
refactoring, and another test image for the ast1030:
wget https://github.com/facebook/openbmc/releases/download/v2021.49.0/fuji.mtd
wget https://github.com/facebook/openbmc/releases/download/v2021.49.0/wedge100.mtd
wget https://github.com/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf
Fuji uses UART1:
qemu-system-arm -machine fuji-bmc \
-drive file=fuji.mtd,format=raw,if=mtd \
-nographic
ast2600-evb uses uart-default=UART5:
qemu-system-arm -machine ast2600-evb \
-drive file=fuji.mtd,format=raw,if=mtd \
-serial null -serial mon:stdio -display none
Wedge100 uses UART3:
qemu-system-arm -machine palmetto-bmc \
-drive file=wedge100.mtd,format=raw,if=mtd \
-serial null -serial null -serial null \
-serial mon:stdio -display none
AST1030 EVB uses UART5:
qemu-system-arm -machine ast1030-evb \
-kernel Y35BCL.elf -nographic
