[oe] [meta-initramfs][PATCH] linux-yocto-tiny-kexecboot: remove obsoleted recipe

[Andrea Adami]

With the changes about the kernel build directories it is now hard to build
two different flavors together witout races.

This recipe was meant as example back then when kexecboot was introduced.
Nowadays the only users are the devices in meta-handheld and they use a more
modern and maintained linux-kexecboot kernel.

-Subject: [PATCH] main.c: revert check on console device
-
-Fix kernel panic because of the missing /dev/console.
-
-Revert Yocto-specific : "check console device file on fs when booting".
-
-The initramfs used in this kernel needs to be of the smallest possible
-size so we save a few kb by deploying an empty /dev which is populated
-after boot by the init (kexecboot checks and recreates the devices
-with or without devtmpfs).
