PATCH 1/1 ARM/dts: omap3: Fix mcbsp2/3 hwmods to be able to probe the drivers for audio

Fixes the following errors:

[    2.318084] omap-mcbsp 49022000.mcbsp: invalid rx DMA channel
[    2.324432] omap-mcbsp 49024000.mcbsp: invalid rx DMA channel

Which is because we failed to link the sidetone hwmod for McBSP2/3. The missing sidetone hwmod link will prevent omap_device_alloc() to append the DMA resources since we - accidentally - end up having the same number of resources provided from DT (IO/IRQ) as we have in hwmod for the McBSP ports without the ST resources.

---

Hi Tony, Benoit,

Can you please take this patch for 3.7 since if we boot with DT audio will not work on BeagleBoard and on boards which uses McBSP2 or 3 for audio.

Thank you,
Peter
