[PATCH v2 04/12] hw/arm/aspeed_ast27x0: Use a table for unimplemented devices

[Jamin Lin <jamin_lin@aspeedtech.com>]

Before this change, each unimplemented device needed its own field in
AspeedSoCState. This made the variable names confusing. For example,
AspeedSoCState has "udc" as an unimplemented device, but
Aspeed2600SoCState also has "udc" as the real UDC model.

Use the unimp_devs table in AspeedSoCClass to describe the
unimplemented devices, and use create_unimplemented_devices() to create
and map them. This makes the code easier to maintain and read. Convert
AST2700 to use them.

No functional change.
