Joel Johnson d8e0b015e8 mvebu: backport ClearFog SPI enablement
Backport Device Tree change first added in kernel 4.19 to enable the SPI
device on ClearFog devices by default. This is tested and working in
snapshot builds with kernel 5.4+, include the change in future 19.07
patch releases.

Subject: [PATCH] ARM: dts: armada388-clearfog: enable spi flash
The SolidRun Armada 388 SOM has the SPI flash populated by default
unless the customer explicitly asks otherwise. Enable support by
default.
