[PATCH] of: Fix RST inline emphasis warnings in of_map_id() kernel-doc

[Vijayanand Jitta]

The @filter_np parameter descriptions in of_map_id() and of_map_msi_id()
contained the text '*filter_np' in prose. Docutils interprets a leading
'*' as the start of RST emphasis (italic), but finds no closing '*',
triggering:

  Documentation/devicetree/kernel-api:11: ./drivers/of/base.c:2134:
  WARNING: Inline emphasis start-string without end-string. [docutils]

  Documentation/devicetree/kernel-api:11: ./drivers/of/base.c:2260:
  WARNING: Inline emphasis start-string without end-string. [docutils]

Fix by wrapping '*filter_np' in double backticks (*filter_np) to
render it as an RST inline code literal, which is also the correct
kernel-doc convention for pointer expressions.
