ARM: davinci: Delete DM644x board files 

The interest of maintaining the DaVinci DM644x board files seems
very low. Patches to convert the EVM board to use GPIO descriptors
has not been reviewed, tested or merged for several merge
windows in a row, see link below.

When I look in the logs for the board files I see nothing but
generic kernel maintenance and no testing on real hardware for
years.

I conclude the DM644x board files are unused and can be deleted.

* The Neuros OSD 2.0 is the hardware component of the Neuros Open
* Internet Television Platform. Hardware is very close to TI
* DM644X-EVM board. It has:
* DM6446M02 module with 256MB NAND, 256MB RAM, TLV320AIC32 AIC,
* USB, Ethernet, SD/MMC, UART, THS8200, TVP7000 for video.
* Additionally realtime clock, IR remote control receiver,
* IR Blaster based on MSP430 (firmware although is different
* from used in DM644X-EVM), internal ATA-6 3.5” HDD drive
* with PATA interface, two muxed red-green leds.
