Omit container name from child identifiers (name-prefix: false)

[aranzaba]

Purpose

x-hdl: name-prefix: false lets a block, repeat, or submap group addresses without putting its own name into generated HDL, doc, or C identifiers. Unlike block-prefix / reg-prefix, it is not inherited — it only applies to the node where you set it.

Why it’s needed

Some blocks exist only for layout/organization. Their names should not pollute signal/register names (e.g. you want ctrl, not grouping_blk_ctrl).

Example

- block:
    name: grouping_blk
    x-hdl:
      name-prefix: false
    children:
    - reg:
        name: ctrl
        access: rw
        width: 32

Default	With name-prefix: false
grouping_blk_ctrl	ctrl

Additional fixes

Updated doc goldens to match intentional generator changes:

• HTML summary links only on REG rows (removed dead BLOCK/SUBMAP/MEMORY links)
• Repeat containers labeled REPEAT instead of BLOCK
