v4 cover Update DA850 to Device tree, SPI MTDPARTS, and DM

This series gives a general update to the DA850 Family. This series ports the device trees from Linux 4.13 and enables DM, DM_SERIAL, DM_SPI, and DM_I2C. At this time, DM_GPIO isn't yet available, but it's pending. During the revamp, it was noted a discrepency between Linux and U-Boot partition mapping when using SPI Flash, so MTDPARTS was updated to make sure the partition mapping in Linux would match the mapping in U-Boot.

A few small additional items are needed to support DM_SPI and DM_SERIAL, so those were added to da850-evm-u-boot.dtsi

Yes. I was having difficulty recognizing the spi-flash without it.

I wasn't happy about it, but it worked.

I am away from my computer for the next week, so I am unable to try anything else for now.

Adam

thanks!
