accel/qaic: Format DBC states table in sysfs ABI documentation

Stephen Rothwell reports htmldocs warnings when merging drm-misc tree:

Documentation/ABI/stable/sysfs-driver-qaic:1: ERROR: Unexpected indentation. [docutils]
Documentation/ABI/stable/sysfs-driver-qaic:1: WARNING: Block quote ends without a blank line; unexpected unindent. [docutils]
Documentation/ABI/stable/sysfs-driver-qaic:1: WARNING: Definition list ends without a blank line; unexpected unindent. [docutils]

These are caused by DMA Bridge channel (DBC) states list in sysfs ABI
docs. Format it as a table to fix them.

 Description:	Represents the current state of DMA Bridge channel (DBC). Below are the possible
-		states,
-		IDLE (0) -		DBC is free and can be activated
-		ASSIGNED (1) -		DBC is activated and a workload is running on device
-		BEFORE_SHUTDOWN (2) -	Sub-system associated with this workload has crashed and
+		states:

+		IDLE (0)		DBC is free and can be activated
+		ASSIGNED (1)		DBC is activated and a workload is running on device
+		BEFORE_SHUTDOWN (2)	Sub-system associated with this workload has crashed and
 					it will shutdown soon
-		AFTER_SHUTDOWN (3) -	Sub-system associated with this workload has crashed and
