{{/*
A Hugo shortcode to include the content generated from the IP description Hjson

Usage: {{< incGenFromIpDesc hjsonPath contentType >}}

hjsonPath: Path to an IP description file in Hjson (ip_name.hjson)
  Relative paths are resolved relative to the directory using the shortcode.
  Absolute paths are resolved relative to REPO_TOP.

  This path could also be a testplan described in Hjson
  (ip_name_testplan.hjson). Testplans may additionally be suffixed with "tags"
  separated with ":" colon delimiter, such as "ip_name_testplan.hjson:foo:bar".
  The tags are extracted from the path and appended at the end to construct the
  path of the generated content, for example:
  "ip_name_testplan.hjson.foo_bar_testplan"

contentType: Type of generated content to include.
  Valid options: testplan, hwcfg, registers

The actual content is rendered as HTML by the util/build_docs.py script and only
included by the shortcode here.
