[PATCH 19/19] tests/boot_linux_console: Test SDHCI and termal sensor on raspi3

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Add a test which loads the root filesystem on a SD card.
Use a kernel recent enough to also test the thermal sensor.

The kernel image comes from:
https://github.com/sakaki-/bcmrpi3-kernel#description

The cpio image used comes from the linux-build-test project:
https://github.com/groeck/linux-build-test
