add support for the davinci am1808 based enbw_cmc board.

This is thought as a RFC patchserie, as this patches
surely have to be discussed:

- ARM: davinci: configure davinci aemif chipselects through OF
not moved to mfd, as mentioned in this discussion:
http://davinci-linux-open-source.1494791.n2.nabble.com/PATCH-arm-davinci-configure-davinci-aemif-chipselects-through-OF-td7059739.html
instead use a phandle in the DTS, so drivers which
uses the davinci aemif, can call davinci_aemif_setup_timing_of()

This is just thought as an RFC ... The enbw_cmc board
support not really need to setup this bus timings, as
they are setup in U-Boot ... but I want to post this,
as I think, it is a nice to have, and I am not really
sure, if this has to be a MFD device (If so, all bus
interfaces for other SoCs should be converted also to
MFD devices) ... as an example how this can be used
I add this to the davinci nand controller OF support
patch, in this patchserie.

- ARM: davinci: mux: add OF support
I want to get rid of the pin setup code in board code ...
This patch introduces a davinci_cfg_reg_of() function,
which davinci drivers can call, if they found a
"pinmux-handle", so used in the following drivers in
this patchserie:

drivers/net/ethernet/ti/davinci_emac
drivers/i2c/busses/i2c-davinci.c
drivers/mtd/nand/davinci_nand.c

- post this board support with USB support, even though
USB is only working with the 10 ms "workaround", posted here:
http://comments.gmane.org/gmane.linux.usb.general/54505
I see this issue also on the AM1808 TMDXEXP1808L evalboard.

- MMC and USB are not using OF support yet, ideas how to port
this are welcome. I need for USB and MMC board specific
callbacks, how to solve this with OF support?
