nrf: Change selected boards to utilize pre-flashed bootloader. The nrf52840-mdk-usb-dongle and pca10050 comes with a pre-flashed bootloader (OpenBootloader). This commit updates the boards "mpconfigboard.mk" to use DFU as default flashing method and set the corresponding BOOTLOADER settings such that nrf52840_open_bootloader_1.2.x.ld linker script is used. The default DFU flashing method can be disabled by issuing "DFU=0" when invoking make. This will lead to "segger" being used as default flashing tool. When using "DFU=0", the linker scripts will not compensate for any MBR and Bootloader region being present, and might overwrite them if they were present. The commit also removes the custom linker script specific to nrf52840-mdk-usb-dongle as it now points to a generic. Updated nrf52840-mdk-usb-dongle's README.md to be more clear on how to deploy the built firmware. The port README.md has also been updated. In the list of target boards a new column has been added to indicate which bootloader is present on the target board. And for consistency, changed all examples in the README.md to use "deploy" instead of "flash".
