regulator: fix bullet lists of regulator_ops comment

Since 89a6a5e5("regulator: add property parsing and callbacks to set protection limits")
which introduced a warning:

Documentation/driver-api/regulator:166: ./include/linux/regulator/driver.h:96: WARNING: Unexpected indentation.
Documentation/driver-api/regulator:166: ./include/linux/regulator/driver.h:98: WARNING: Block quote ends without a blank line; unexpected unindent.

Let's fix them.
