This adapts to the oe-core rework to enforce a separate directory
for unpacking local sources (UNPACKDIR) instead of directly using
WORKDIR.
Follows the preliminary guideline from:

The Raspberry Pi 4 board can boot the image from USB memory.
But current meta-raspberrypi supports only SD boot.
This commit allows switching SD boot to other device.
For example, if you want to use USB boot, please define
the following parameters in your conf/local.conf file.
CMDLINE_ROOT_PARTITION = "/dev/sda2"
BOOT_MEDIA = "usb"
v4: Update extra-build-config.md to explain more detail for new variable.
v3: Changed variable name to "BOOT_MEDIA" (was "BOOT_DEVTIPE").
v2: Set existing microSD parameter as default. User can overwrite
some parameters.

Modify boot.cmd.in from recipe rpi-u-boot-scr to create uboot.env
in the /boot partition when using U-Boot. This change is required
to successfully run fw_printenv from the user space.

Add u-boot-default-script to the PROVIDES variable to make easier to
replace boot script in another layer just by changing
PREFERRED_PROVIDER_u-boot-default-script variable. Set rpi-u-boot-scr as
the default provider for meta-raspberrypi.

We have a few recipes which only deploy files that go into the boot partition
and do not create packages to be installed into the rootfs. These recipes don't
need to run the usual packaging tasks so we can drop them to speed up the build
a little.
We also have a bunch of recipes that don't need the usual toolchain as they just
copy files or invoke native commands like `mkimage`. So to speed up the build a
little more we can set INHIBIT_DEFAULT_DEPS to avoid an unnecessary dependency
on the toolchain.

For raspberrypi3-64 we need to use the Image or Image.gz format with u-boot
instead of the legacy uImage format. We also need to issue the 'booti' command
to boot the kernel instead of 'bootm'.

* bitbake is using re.match, so raspberrypi actually matches with anything
^raspberrypi.* which currently works, but it will also match with hypothetical
raspberrypi-is-no-more-this-is-banana-now MACHINE which isn't intended by
this COMPATIBLE_MACHINE.

A patch is backported to check if the firmware loaded a device tree blob
into memory and set the fdt_addr variable if it is found. The U-Boot
script will then read the command line arguments generated by the
firmware from the device tree and boot the kernel with the command
line arguments and the loaded device tree.
This allows things like MAC address, board revision and serial number
to be correctly configured and options in config.txt to be used.
An additional patch is backported and further changes are made to support
this.

Upstream u-boot searches the boot partition for a script named 'boot.scr'. If
this file exists it is executed as a sequence of u-boot commands in order to
boot the system. This script must be compiled using the mkimage command to
ensure that it is understood by u-boot.
