Bagas Sanjaya 4dc7c58023 habanalabs: Fix list of /sys/class/habanalabs/hl<n>/status 
Stephen Rothwell reported htmldocs warnings when merging accel tree:

Documentation/ABI/testing/sysfs-driver-habanalabs:201: ERROR: Unexpected indentation.
Documentation/ABI/testing/sysfs-driver-habanalabs:201: WARNING: Block quote ends without a blank line; unexpected unindent.
Documentation/ABI/testing/sysfs-driver-habanalabs:201: ERROR: Unexpected indentation.
Documentation/ABI/testing/sysfs-driver-habanalabs:201: WARNING: Block quote ends without a blank line; unexpected unindent.

Fix these by fixing alignment of list of card status returned by
/sys/class/habanalabs/hl<n>/status.
