arm-bsp/docs: corstone1000: Drop A320 content from base documentation
Remove Cortex-A320-specific content from the base Corstone-1000 documentation. Drop the A320-only sections, commands, notes, and subsystem image from the shared Corstone-1000 software architecture and user guide now that the platform is documented in its own standalone document set.

Corstone-1000 with Cortex-A320 Variant
|
||||
**************************************
|
||||
|
||||
This variant of the Corstone-1000 platform replaces the Host System's Cortex-A35 processor
|
||||
with a Cortex-A320. In this configuration, the optional External System (previously a Cortex-M3)
|
||||
is replaced by an Arm Ethos-U85 Neural Processing Unit (NPU).
|
||||
The Ethos-U85 runs in the direct drive configuration, where the Host System is responsible for managing the NPU directly.
