[PULL 13/23] docs/system/arm/aspeed: move AST2700 content to new section

["Cédric Le Goater" <clg@redhat.com>]

From: Jamin Lin <jamin_lin@aspeedtech.com>

Moved AST2700-related content from the general Aspeed board list into a
dedicated section for Aspeed 2700 family boards. Improves clarity and
readability.
