ath79: add support for YunCore TFTP image generation
YunCore QCA9k based devices released in 2019 require a custom TFTP image for U-Boot built-in recovery mode (triggered with reset button). Image has to be prepended with 'YUNCORE' keyword followed by U-Boot CLI commands which will be executed later. Images without the custom header will be ignored by U-Boot. To be able to support both the vendor firmware (QSDK) and OpenWrt flash layouts, used here commands change the 'bootcmd' before flashing image. This commit adds generic helper script for YunCore devices with 16 MB of flash and enables TFTP image generation for A770 model.
