DaVinci DT updates for v3.12 

----------------------------
 
 This set of patches add ethernet DT nodes
 for DA850 and also remove now unneeded
 specification of UART clock frequency so
 kernel can now boot irrespective of what
 the bootloader setting of UART frequency is.

specification of UART clock frequency so
kernel can now boot irrespective of what
the bootloader setting of UART frequency is.

* tag 'davinci-for-v3.12/dt' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
  ARM: davinci: da850: do not specify clock_frequency for UART DT node
  ARM: davinci: da850: add DT node for ethernet
  ARM: davinci: da850: add OF_DEV_AUXDATA entry for davinci_emac
  ARM: davinci: da850: add OF_DEV_AUXDATA entry for mdio.
  ARM: davinci: da850: add DT node for mdio device
