[PATCH] platform/raspberrypi: vchiq: Fix kernel-doc Return section

[Tomasz Unger <tomasz.unger@yahoo.pl>]

scripts/kernel-doc -Wall reports that vchiq_register_chrdev() has no
description of its return value:

  Warning: drivers/platform/raspberrypi/vchiq-interface/vchiq_dev.c:1341
  No description found for return value of 'vchiq_register_chrdev'

The comment does describe it, but in a free-form "Returns 0 on success
..." sentence that kernel-doc does not recognize. Convert it to a
"Return:" section.

No functional change.
