[PATCH 5/5] tests/boot_linux_console: Add sdcard test for the Exynos4210

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

This test boots a Linux kernel on a smdkc210 board and verify
the serial output is working.

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

Since this test is not reliable due to clock timing issues,
it is disabled with the 'skip' property.
