Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

explicitly include the correct includes.

Add documentation to describe the access to the pmu hardware counters from
userspace.

Userspace counter access only works on heterogeneous systems with some
restrictions. The userspace process must be pinned to a homogeneous
subset of CPUs and must open the corresponding PMU for those CPUs. This
commit adds a test implementing these requirements.

v6
Add arm64 specific tests for 32-bit and 64-bit counter user access. On
arm64, counters default to 32-bit unless attr.config1:0 is set to 1. In
order to enable user access for 64-bit counters, attr.config1 must be set
to 3.

v6:
- New patch

tools/perf/arch
Add the arm64 variants for read_perf_counter() and read_timestamp().
Unfortunately the counter number is encoded into the instruction, so the
code is a bit verbose to enumerate all possible counters.

v7:
- Move enabling of libperf user read test for arm64
disable access on each PMU.
Note that x86 also supports writing '2' to globally enable user access.
As there's not existing userspace support to worry about, this shouldn't
be necessary for Arm. It could be added later if the need arises.

Peter Z says (event->oncpu == smp_processor_id()) in the user page
update is always true, but my testing says otherwise[1].
v7:
- Clear disabled counters when user access is enabled for a task to
avoid leaking other tasks counter data.
- Rework context swi
The arm64 PMU driver needs to retrieve the struct arm_pmu pointer for
the current CPU. As the common code already maintains this with the
percpu cpu_armpmu, let's make it global.
