* Helios4: Add workaround for SPI and SATA concurrent access issue
Concurrent access on SPI NOR and SATA drives can lead to unstable SATA.
Therefore as workaround, disable SATA controller when SPI flash access
is needed and make it as user configurable item in armbianEnv.txt
This workaround might applies to Clearfog too.

* Helios4: Add SPI bootloader install feature
This will allow to use nand-sata-install to perform the following operations on Helios4 :
- Install bootloader to SPI NOR Flash (Option 5 in Menu).
- Copy RootFS to USB storage in order to boot from SPI with RootFS on USB (Option 6 in Menu).
* Unmount temp mount points in create_armbian() instead of hardcoded /dev/sda
Based on work of David Huang https://github.com/hjc4869 Changed in the transition:
- firefly family was renamed to rk3399, which we actually never started to use. It was made for Odroid N1, which will never be sold
- adjusted compiler toolchain2 parameter
- added standard wireless drivers
- kernel config with the following changes: Docker dependencies, ZRAM, CPUfreq info, ...
- added upstream patches
- made test Ubuntu Bionic desktop and CLI Stretch build, bootlog: http://ix.io/1jVu
TBD: wifi and BT support, mainline kernel, ...
- merging C2 and Meson family on the source level, C2 is still making own kernels, but sources, patches and configs are the same
- merged boot scripts for meson family. support for non existing legacy kernel was dropped from boot scripts, added UUID support, armbianEnv.txt
- Meson default remain on 4.14.y, NEXT moved to 4.17.y and DEV remains on master
- remove deprecated patches, remove wrong permissions in patches
- tested on C2, K2 and Le Potate. USB troubles are still present and common, while K2 and Lepotato might have boot/reboot troubles on 4.16+
- boards configuration cleanup
- moving K2 to the supported list. It's the same level of support as Le Potato
