Introduce "aspeed_load_vbootrom()" to support loading a virtual boot ROM image
into the vbootrom memory region, using the "-bios" command-line option.
Introduce a new "vbootrom" field in the AspeedMachineClass to indicate whether
a machine supports the virtual boot ROM region.
Set this field to true by default for the AST2700-A0 and AST2700-A1 EVB
machines.

Introduce a new vbootrom memory region. The region is mapped at address
"0x00000000" and has a size of 128KB, identical to the SRAM region size.
This memory region is intended for loading a vbootrom image file as part of the
boot process.
The vbootrom registered in the SoC's address space using the ASPEED_DEV_VBOOTROM
index.

AST27x0 has 4 EHCI controllers, where each CPU and I/O die has 2
instances. This patch use existing TYPE_PLATFORM_EHCI. After wiring up
the EHCI controller, the ast2700a1-evb can find up to 4 USB EHCI
interfaces.

Merge into INDEX_op_{ld,st,ld2,st2}, where "2" indicates that two
inputs or outputs are required. This simplifies the processing of
i64/i128 depending on host word size.

Liveness needs to track carry-live state in order to
determine if the (hidden) output of the opcode is used.
Code generation needs to track carry-live state in order
to avoid clobbering cpu flags when loading constants.
So far, output routines and backends are unchanged.
