[PATCH 1/2] Documentation: PCI: Use code-block block for scratchpad registers diagram

[Bagas Sanjaya]

The diagram in "Scratchpad Registers" isn't formatted inside code block,
hence triggers indentation warning:

Documentation/PCI/endpoint/pci-vntb-function.rst:82: WARNING: Unexpected indentation.

Fix the warning by using code-block directive to format the diagram
inside code block, as in other diagrams in Documentation/. While at it,
unindent the preceeding text.
