scsi: docs: ABI: sysfs-driver-ufs: Rectify table formatting

Commit 0b2894cd0fdf ("scsi: docs: ABI: sysfs-driver-ufs: Add DeepSleep
power mode") adds new entries in tables of sysfs-driver-ufs ABI
documentation, but formatted the table incorrectly.

Hence, make htmldocs warns:

  ./Documentation/ABI/testing/sysfs-driver-ufs:{915,956}:
  WARNING: Malformed table. Text in column margin in table line 15.

Rectify table formatting for DeepSleep power mode.
