* 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
