DaVinci SoC changes for v3.11 

This pull request moves DaVinci EDMA library to
 arch/arm/common so it can be used by OMAP based AM335x.
 This is a temporary step until all drivers are converted
 to use the dmaengine driver in drivers/dma/edma.c.
 
 Several drivers like SPI, MMC/SD have already been converted.
 Some like audio are pending.
 
 The other two patches in the pull request are cleanup in nature.

DaVinci SoC changes for v3.11

This pull request moves DaVinci EDMA library to
arch/arm/common so it can be used by OMAP based AM335x.
This is a temporary step until all drivers are converted
to use the dmaengine driver in drivers/dma/edma.c.

Several drivers like SPI, MMC/SD have already been converted.
Some like audio are pending.

The other two patches in the pull request are cleanup in nature.

* tag 'davinci-for-v3.11/soc-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
  ARM: edma: remove unused transfer controller handlers
  ARM: davinci: move private EDMA API to arm/common
  ARM: davinci: remove __init atrribute from function declaration
