From: Jamin Lin <jamin_lin@aspeedtech.com>

Refactor the AST27x0 TSP implementation to use the unified
Aspeed27x0CoprocessorState, matching the prior SSP change and removing the
duplicated Aspeed27x0TSPSoCState.

Key updates:
- Delete Aspeed27x0TSPSoCState and reuse Aspeed27x0CoprocessorState.

Update Ast2700FCState to declare tsp as Aspeed27x0CoprocessorState.
This aligns TSP with SSP on a single coprocessor state type, reducing code
duplication and simplifying maintenance.

No functional change.
