Stephen Boyd reworked some Qualcomm USB code earlier this year.
The result requires a few different config options to be enabled
in order for the USB on the DragonBoard 410c to continue working,
but these were never added to arm64 "defconfig".  As a result, USB
on that board stopped working during the v4.13-rc1 merge window.

Re-enable this functionality by setting the needed config options
in the arm64 "defconfig" file.

commit cee22a15 ("workqueues: Introduce new flag WQ_POWER_EFFICIENT
for power oriented workqueues") introduced the concept of power
efficient workqueues (4 years back), but it was never enabled in
upstream kernel configs.

Power efficient workqueues are simply marked as "unbound," so that jobs
queued to them can run on any CPU in the system. It leaves the target
CPU selection to the scheduler, which is the best place for such
decision making. This improves power efficiency for workqueues which are
otherwise pinned to a CPU.

Enable it for ARM64 platforms as ARM platforms were the main target for
the introduction of power efficient workqueues.

Tests showed, that under certain conditions, the summary number of jiffies
spent on softirq/idle, which are counted by system statistics can be even
below 10% of expected value, resulting in false load presentation.

The issue was observed on the quad-core Marvell Armada 8k SoC, whose two
10G ports were bound into L2 bridge. Load was controlled by bidirectional
UDP traffic, produced by a packet generator. Under such condition,
the dominant load is softirq. With 100% single CPU occupation or without
any activity (all CPUs 100% idle), total number of jiffies is 10000 (2500
per each core) in 10s interval. Also with other kind of load this was
true.

However below a saturation threshold it was observed, that with CPU which
was occupied almost by softirqs only, the statistic were awkward. See
the mpstat output:

CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle
all 0.00  0.00 0.13    0.00 0.00  0.55   0.00   0.00   0.00 99.32
  0 0.00  0.00 0.00    0.00 0.00 23.08   0.00   0.00   0.00 76.92
  1 0.00  0.00 0.40    0.00 0.00  0.00   0.00   0.00   0.00 99.60
  2 0.00  0.00 0.00    0.00 0.00  0.00   0.00   0.00   0.00 100.00
  3 0.00  0.00 0.00    0.00 0.00  0.00   0.00   0.00   0.00 100.00

Above would mean basically no total load, debug CPU0 occupied in 25%.
Raw statistics, printed every 10s from /proc/stat unveiled a root
cause - summary idle/softirq jiffies on loaded CPU were below 200,
i.e. over 90% samples lost. All problems were gone after enabling
fine granulity IRQ time accounting.

This patch fixes possible wrong statistics processing by enabling
CONFIG_IRQ_TIME_ACCOUNTING for arm64 platfroms, which is by
default done on other architectures, e.g. x86 and arm. Tests
showed no noticeable performance penalty, nor stability impact.
