drivers/perf: hisi: Add TLP filter support

2022-11-29T14:30:55Z

The PMU support to filter the TLP when counting the bandwidth with below options: - only count the TLP headers - only count the TLP payloads - count both TLP headers and payloads In the current driver it's default to count the TLP payloads only, which will have an implicity side effects that on the traffic only have header only TLPs, we'll get no data. Make this user configuration through "len_mode" parameter and make it default to count both TLP headers and payloads when user not specified. Also update the documentation for it.

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

2022-11-29T14:30:54Z

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.
