The micro-USB on the SinA33 has a somewhat interesting design in the sense
that it has a micro USB connector, but the VBUS is (supposed to be)
controlled through an (unpopulated) jumper.
Obviously, that doesn't work really well, and only the peripheral mode
really works. Still enable it.

Though the mmc core driver will continue to support the legacy
"enable-sdio-wakeup" property to enable SDIO as the wakeup source,
"wakeup-source" is the new standard binding.
This patch replaces the legacy "enable-sdio-wakeup" with the unified
"wakeup-source" property in order to avoid any further copy-paste
duplication.

With the introduction of cpu capacity-dmips-mhz bindings, CPU capacities
can now be calculated from values extracted from DT and information
coming from cpufreq. Add parsing of DT information at boot time, and
complement it with cpufreq information. We keep code that can produce
same information, based on different DT properties and hard-coded
values, as fall-back for backward compatibility.
Caveat: the information provided by this patch will start to be used in
the future. We need to #define arch_scale_cpu_capacity to something
provided in arch, so that scheduler's default implementation (which gets
used if arch_scale_cpu_capacity is not defined) is overwritten.

Group validation expects all events to be of the same PMU; however
is_uncore_pmu() is too wide, it matches _all_ uncore events, even
across PMUs.
This triggers failure when we group different events from different
uncore PMUs, like:
perf stat -vv -e '{uncore_cbox_0/config=0x0334/,uncore_qpi_0/event=1/}' -a sleep 1
Fix is_uncore_pmu() by only matching events to the box at hand.
Note that generic code; ran after this step; will disallow this
mixture of PMU events.
