linux-raspberrypi enables CONFIG_ANDROID_BINDERFS by
default which is the cause of binder devices not being 
generated in /dev .

Disabling CONFIG_ANDROID_BINDERFS to have /dev/binder
needed by openharmony system.

openharmony.inc is also included by linux-raspberrypi kernel, 
therefore moving qemu specific kernel configs into 
linux-yocto_%.bbappend

Currently kernel configs and patches are applied only to linux-yocto.
Adding linux-raspberrypi_%.bbappend to apply openharmony kernel patches
also to linux-raspberrypi kernel.

Set linux-raspberrypi preferred kernel version to 5.10 to align with linux-yocto
version. This allows `driver-add-hilog-and-hievent-buffer-management-drive.patch`
to be correctly applied.

rename directory to align with the upstream directory structure 
which is recipes-kernel/linux instead of recipes-kernel/linux-yocto

The OpenHarmony kernel features will be needed in other Linux recipes, so we
move the needed bitbake code to an openharmony.inc file which can then be
included in such recipes.

Instead of hardcoding an `openharmony` override, this introduce an
`openharmony` distro feature which (when enabled) will add a
`df-openharmony` override.

The `openharmony` distro feature will also gate the `openharmony-3.0`
and `openharmony-3.1` overrides, so they are only active when `openharmony`
is enabled.

configuration which enables "openharmony" in its DISTROOVERRIDES.

OpenHarmony requires Android Shared Memory kernel support which is currently
under drivers/staging/android/ and therefore the header file is not being
installed.
