Device tree support for Davinci Machine driver

When the board boots with device tree, the driver will receive card,
codec, dai interface details (like the card name, DAPM routing map,
phandle for the audio components described in the dts file, codec mclk
speed). The card will be set up based on this information. Since the
routing is provided via DT we can mark the card fully routed so core
can take care of disconnecting the unused pins.

AM33xx uses same McASP IP as the Davinci Platform. This patch updates
Kconfig and makefile to enable build for McASP, PCM & Codec drivers.

The serial-dir array gives this information so there is no need to have the
num-serializer property in DT description.
Just ignore the property in the driver the DTS files can be updated
separately without regression.
Update the documentation at the same time for davinci-mcasp

Makes interrupts property optional as the interrupts are not currently
used by the driver and adds interrupt-names property to name listed
interrupts. Currently know interrupt names are "tx" and "rx".

- Improve tdm-slots propery description

- Improve op-mode property description

- Add pinctrl-names and pinctrl-0 properties

- Remove #address-cells and #size-cells as they are not needed.

- Bracket named interrupts property tuples for uniformity.

- Add missing "for" to serial-dir prop in DT bindings doc.

Extract DMA channels directly from DT as they can not be found from
platform resources anymore. This is a work-around until davinci audio
driver is updated to use dmaengine.

This patch adds a separate register location for data port registers to
mcasp DT bindings. On am33xx SoCs the McASP registers are mapped
trough L4 interconnect, but data port registers are also mapped trough
L3 bus to a different memory location.

While reporting the jack status snd_soc_jack_report() invokes snd_soc_dapm_sync()
always. This should be required when we have pins associated with jack and
reporting enables or disables these.
So add a check for this case

Pull btrfs fix from Chris Mason:
 "Sage hit a deadlock with ceph on btrfs, and Josef tracked it down to a
  regression in our initial rc1 pull.  When doing nocow writes we were
  sometimes starting a transaction with locks held"

Pull ACPI and power management fixes from Rafael Wysocki:

 - intel_pstate fix for misbehavior after system resume if sysfs
   attributes are set in a specific way before the corresponding suspend
   from Dirk Brandewie.

 - A recent intel_pstate fix has no effect if unsigned long is 32-bit,
   so fix it up to cover that case as well.

 - The s3c64xx cpufreq driver was not updated when the index field of
   struct cpufreq_frequency_table was replaced with driver_data, so
   update it now.  From Charles Keepax.

 - The Kconfig help text for ACPI_BUTTON still refers to
   /proc/acpi/event that has been dropped recently, so modify it to
   remove that reference.  From Krzysztof Mazur.

 - A Lan Tianyu's change adds a missing mutex unlock to an error code
   path in acpi_resume_power_resources().

 - Some code related to ACPI power resources, whose very purpose is
   questionable to put it lightly, turns out to cause problems to happen
   during testing on real systems, so remove it completely (we may
   revisit that in the future if there's a compelling enough reason).
   From Rafael J Wysocki and Aaron Lu.
