[PATCH] docs: perf: cleanup fujitsu_uncore_pmu.rst and fix htmldocs warnings/errors

[Gopi Krishna Menon <krishnagopi487@gmail.com>]

- Adjust spacing around list and sections for better readability.
- Use definition lists for defining events.
- Replace block quotes with code blocks where appropriate.

Fixes the following htmldocs errors/warnings:
Documentation/admin-guide/perf/fujitsu_uncore_pmu.rst:20: ERROR: Unexpected indentation.
Documentation/admin-guide/perf/fujitsu_uncore_pmu.rst:23: WARNING: Block quote ends without a blank line; unexpected unindent.
Documentation/admin-guide/perf/fujitsu_uncore_pmu.rst:28: ERROR: Unexpected indentation.
Documentation/admin-guide/perf/fujitsu_uncore_pmu.rst:29: WARNING: Block quote ends without a blank line; unexpected unindent.
Documentation/admin-guide/perf/fujitsu_uncore_pmu.rst:81: ERROR: Unexpected indentation.
Documentation/admin-guide/perf/fujitsu_uncore_pmu.rst:82: WARNING: Block quote ends without a blank line; unexpected unindent.

 This driver supports the Uncore MAC PMUs and the Uncore PCI PMUs found
 in Fujitsu chips.

 Each MAC PMU on these chips is exposed as a uncore perf PMU with device name
-mac_iod<iod>_mac<mac>_ch<ch>.

 This driver supports the following events for MAC:
-- cycles
+--------------------------------------------------
+

+
+read-count:
   This event counts the number of read requests to MAC.

 Given that these are uncore PMUs the driver does not support sampling, therefore
 "perf record" will not work. Per-task perf sessions are not supported.
