The raspberry pi 4 variant has a BCM2711 chip, however it still
uses the same boot files as the BCM2835 used in previous generations.
This change generalizes the naming of the directory generated in the
$DEPLOY_DIR to avoid the implication that the files are only
meant for the BCM2835.

* use INITRAMFS_SYMLINK_NAME from new kernel-artifact-names.bbclass
instead of KERNEL_INITRAMFS
* the documentation says that KERNEL_INITRAMFS should be used to
define extension of initramfs, but in linux-raspberrypi.inc it's
defined only to 1 or empty based on INITRAMFS_IMAGE_BUNDLE variable
and I don't see any code in meta-raspberry or oe-core which would
use KERNEL_INITRAMFS to actualy name the initramfs artifact to create:
${DEPLOY_DIR_IMAGE}/${KERNEL_IMAGETYPE}${KERNEL_INITRAMFS}-${MACHINE}.bin
used in classes/sdcard_image-rpi.bbclass
* also fix the assumption that there is -${MACHINE} suffix in:
${DEPLOY_DIR_IMAGE}/${KERNEL_IMAGETYPE}${KERNEL_INITRAMFS}-${MACHINE}.bin
because that's defined as KERNEL_IMAGE_SYMLINK_NAME and some DISTROs
might use different value
* this depends on oe-core changes which were merged today:

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.

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

The kernel debugger over console (kgdboc) parameter is being added
unconditionally to the kernel command line but this means that the
kernel will stop and wait for gdb to attach in case of a exception
or when sending a sysrq-g key. This behaviour may not be what most
users wants that are not remotely debugging the kernel over serial
console so make it optional by adding a ENABLE_KGDB config option.
