docs: perf: convert to ReST

Rename the perf documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

-ARM DynamIQ Shared Unit (DSU) PMU
-==================================
-
-ARM DynamIQ Shared Unit integrates one or more cores with an L3 memory system,
-control logic and external interfaces to form a multicore cluster. The PMU
-allows counting the various events related to the L3 cache, Snoop Control Unit
-etc, using 32bit independent counters. It also provides a 64bit cycle counter.
-
-The PMU can only be accessed via CPU system registers and are common to the
-cores connected to the same DSU. Like most of the other uncore PMUs, DSU
-PMU doesn't support process specific events and cannot be used in sampling mode.
-
-The DSU provides a bitmap for a subset of implemented events via hardware
-registers. There is no way for the driver to determine if the other events
-are available or not. Hence the driver exposes only those events advertised
-by the DSU, in "events" directory under :
-
-  /sys/bus/event_sources/devices/arm_dsu_<N>/
-
-The user should refer to the TRM of the product to figure out the supported events
-and use the raw event code for the unlisted events.
-
-The driver also exposes the CPUs connected to the DSU instance in "associated_cpus".

-e.g usage :
-
-	perf stat -a -e arm_dsu_0/cycles/
