Fix AM335x-evm analog audio support

The RFC version of patches can been found here:
http://mailman.alsa-project.org/pipermail/alsa-devel/2013-September/066178.html
The v2 version of patches can be found here:
http://mailman.alsa-project.org/pipermail/alsa-devel/2013-September/066379.html

Changes since v2
[PATCH v2 01/11] ASoC: davinci-evm: Move sysclk logic away from evm_hw_params
- no change
[PATCH v2 02/11] ASoC: davinci-evm: Add device tree binding
- no change
[PATCH v2 03/11] ASoC: davinci-mcasp: Add DMA register locations to DT
- no change
[PATCH v2 04/11] ASoC: davinci-mcasp: Extract DMA channels directly from DT
- no change
[PATCH v2 05/11] ASoC: davinci-mcasp: Remove interrupt property from DT bindin
- restore binding but make it optional and add interrupt-names property
[PATCH v2 06/11] ASoC: davinci: Add support for AM33xx SoC Audio
- SND_DAVINCI_SOC help "Machine driver for ..." -> "Platform driver for ..."
- SND_AM33XX_SOC_EVM depends on SND_DAVINCI_SOC && SOC_AM33XX
- SND_AM33XX_SOC_EVM does not selcet SND_DAVINCI_SOC
[PATCH v2 07/11] ASoC: tlv320aic3x: Add regulators to DT bindings document
- no change
[PATCH v2 08/11] ASoC: tlv320aic3x: Add codec pins to DT bindings document
- no change
[PATCH v2 09/11] ARM/dts: am33xx: Add mcasp0 and mcasp1 device tree entries
- restore interrupt property and add interrupt-names property
[PATCH v2 10/11] ARM/dts: am33xx: mcasp: Add new dma register location to reg-property
- no change
[PATCH v2 11/11] ARM/dts: am335x-evm: Add audio support for am335x-evm.dts
- no change

Changes from RFC to v2
- Dropped out "ASoC: davinci-mcasp: Add pinctrl support" since driver core is taking care of this now.
- Cleanup am33xx audio build
- Add regulators to tlv320aic3x DT binding document
- Remove dm365-voice-codec-audio DT support as it has never
been tested an probably does not work
- Add output pins and Line In connector to davinci-evm-audio DT binding doc
- Remove asp_chan_q and ram_chan_q properties from mcasp DT node in DT mode mcasp is hardcoded to event queue 0 (highest priority)
- Add pins to tlv320aic3x DT bindings document. If I misunderstood Marks comment and this patch is not needed, then just leave it out
Changes based on TI internal discussions
- Move system clock rate logic away from from evm_hw_params soc-op
- Remove unnecesary #if defined(CONFIG_OF) from davinci-evm.c
- Make dma property DT binding document more exact
- Add only "dma" reg location instead of separate "dma-tx" and "dma-rx"
- Primarily look for "mpu" reg property, but fall back to index 0 if not found
- Remove interrupt property from mcasp DT node as it is not used
- Remove #address-cells and #size-cells mcasp properties as they are not needed

This set of patches fixes the basic audio support for am335x-evm. It should also be relatively simple to add the necessary nodes to relevant dts files to get BeagleBone + AudioCape and am335x-evmsk working too.

The patch set depends on following patches:

[PATCH v11 4/8] ARM: dts: add AM33XX EDMA support

     https://lkml.org/lkml/2013/6/18/49

[PATCH v11 5/8] ARM: dts: add AM33XX SPI DMA support

     https://lkml.org/lkml/2013/6/18/55

[PATCH v2] ARM: EDMA: Fix clearing of unused list for DT DMA resources

     https://lkml.org/lkml/2013/7/22/441

I have tried my best not to break the existing support for older davinci boards, but since I do not have those boards I can not be sure.

Some commit comments refer to a dmaengine based davinci audio implementation which is planned for but nothing has been done yet.

Best regards,
Jyri
