staging: line6: List out capabilities individually

The `LINE6_CAP_CTRL_PCM_HW' macro combines three capabilities to save
horizontal space when defining the properties entries.  Now that these
are no longer limited to single lines this is not such a concern.
Specify capabilities individually when defining each property for
better clarity.
