Currently, building linux-raspberrypi with "devtool build" breaks
because ${B}.config doesn't yet exist when do_configure_prepend runs.
Fix this by taking some logic from kernel.bbclass do_configure to populate
${B}.config before do_configure_prepend.
The full explanation for why this is necessary is fairly complex:
- In devtool builds, externalsrc.bbclass gets inherited and sets a list of
SRCTREECOVEREDTASKS, which don't get run because they affect the source tree
and, when using devtool, we want the developer's changes to be the single
source of truth. kernel-yocto.bbclass adds do_kernel_configme to
SRCTREECOVEREDTASKS, so it doesn't run in a devtool build., In a normal
non-devtool build, do_kernel_configme creates ${B}.config.
- Normally (e.g. in linux-yocto), it would be OK that do_kernel_configme
doesn't run, because the first few lines of do_configure in kernel.bbclass
populate ${B}.config from either ${S}.config (if it exists) for custom
developer changes, or otherwise from ${WORDIR}/defconfig.
- In linux-raspberrypi, we add do_configure_prepend, which tweaks
${B}.config. Since this runs *before* the kernel.bbclass do_configure,
${B}.config doesn't yet exist and we hit an error. Thus we need to move
the logic from do_configure up to before our do_configure_prepend. Because
we are copying only a portion of do_configure and not the whole thing,
there is no clean way to do it using OE functionality, so we just
copy-and-paste.

This command is done (with more correct flags) in kernel.bbclass's
kernel_do_configure. Since we inherit that and prepend to it, we don't
need to run it ourselves, as we end up just running it twice.

Currently, we are installing the rpi custom txt and fw files whenever
the meta-raspberrypi layer is included in bblayers.conf. This breaks
other machines that need to use the bcm43430 drivers but with alternate
txt or fw files.
Install these files only when "rpi" is in MACHINEOVERRIDES.

There is no reason to continue supporting pre-4.8 series kernels so we can move

There is no need to have 2 separate inc files any more and the existing code has
several duplications.

The only remaining function in linux-raspberrypi-base was split_overlays() which
is used in the sdcard_image-rpi class. So we can move this function over and
drop the now-empty linux-raspberrypi-base class.

* The kerneltype variable is not used anywhere after being set.
* The manipulation of KERNEL_DEVICETREE is effectively a no-op, we read the
current value in get_dts() and store this back into the same variable.

The version of this firmware provided by linux-firmware is 7.45.41.26. This
version seems to have connectivity issues when bonding interfaces. Raspbian
included an updated version (7.45.41.46) which tested, proved to fix this
problem (see https://github.com/resin-os/meta-resin/issues/812).
The version Raspbian is providing is not yet in linux-firmware as they have it
directly from Cypress (see https://github.com/RPi-Distro/repo/issues/88).
Besides the issue described above, it fixes various other issues including a
broadpwn fix.
Hopefully this version, or a newer one, will end up in upstream soon. In order
to catch when that happens and stop overwriting this firmware, a check is added
in the racipe based on the md5sum of the current shipped firmware.
In terms of ditribution license, we got an informal one in the github thread
mentioned above.

OE currently builds dtb files with its own custom targets by
specifying each dtb file as makefile target, this creates bad
dtb for rpi64 bit. This patch calles 'make dtbs' at the end
which regenerates the correct dtb files
This makes the vc4 initialize properly on rpi64

This makes the linux-raspberrypi_dev recipe more flexible by allowing

The development branches of linux-raspberrypi are rebased frequently. To
avoid fetch failures caused by out-of-date git hashes we need to use
AUTOREV.
LINUX_VERSION may need to be overridden in local.conf to match the
upstream version.
