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.

Fixes#1095 where setting cma to a lower value affects the ability of
libcamera-apps to capture higher resolution images.

Otherwise the shell snippet fails with `bad syntax` when `CMDLINE`
contains special characters like `${...}` (useful to insert a U-Boot
variable in `cmdline.txt`).

The cmdline.txt file generated by this recipe includes machine-specific
information so we should set PACKAGE_ARCH appropriately.

With current recipe formatting CMDLINE variable contains
many unnecessary white spaces. This patch allow to drop
unnecessary spaces at the moment of writing them to
cmdline.txt. This will improve readability of cmdline.txt,
/proc/cmdline and dmesg output.

Instead of generating cmdline.txt in the kernel recipe, it is generated
in a standalone recipe and pulled in as a dependency of the bootfiles
recipe. This simplifies the process of using a linux-yocto,
linux-mainline or similiar kernel recipe instead of linux-raspberrypi.
In the rpi-cmdline recipe the command line is built from fragments which
can all be easily overridden. The variables `SERIAL` and `CMA` are
renamed to `CMDLINE_SERIAL` and `CMDLINE_CMA` for consistency. The
cmdline.txt file is created in the do_compile step to allow further
customisation via do_compile_append if needed.
