[PATCH v1 9/9] docs/system/arm/aspeed: Add AST1080 Platform Root of Trust evaluation board

[Jamin Lin <jamin_lin@aspeedtech.com>]

Update the Aspeed AST10x0 documentation to include the AST1080
evaluation board.

The documentation now describes:
- AST1080 as a Platform Root of Trust processor
- AST1080 Cortex-M4F CPU frequency running at 400 MHz

Also add the ast1080-evb machine entry to the supported AST10x0 SoC
based machine list.
