Documentation: perf: Indent filter options list of hisi-pcie-pmu

The "Filter options" list have a rather ugly indentation. Also, the first
paragraph after list name is rendered without separator (as continuation
from the name).

Align the list by indenting the list items and add a blank line
separator for each list name.

 2. Trigger filter
-Event statistics start when the first time TLP length is greater/smaller
-than trigger condition. You can set the trigger condition by writing "trig_len",
-and set the trigger mode by writing "trig_mode". This filter can only be used
-in bandwidth events.
 
-For example, "trig_len=4" means trigger condition is 2^4 DW, "trig_mode=0"
-means statistics start when TLP length > trigger condition, "trig_mode=1"
-means start when TLP length < condition.

 3. Threshold filter
-Counter counts when TLP length within the specified range. You can set the
-threshold by writing "thr_len", and set the threshold mode by writing
-"thr_mode". This filter can only be used in bandwidth events.
 
-For example, "thr_len=4" means threshold is 2^4 DW, "thr_mode=0" means
-counter counts when TLP length >= threshold, and "thr_mode=1" means counts
-when TLP length < threshold.
