Audio memory to memory virtual driver use video memory to memory

device type is VFL_TYPE_AUDIO and device cap type is V4L2_CAP_AUDIO_M2M.
The device_run function is a dummy function, which is simply
copy the data from input buffer to output
Implement the ASRC memory to memory function using
the v4l2 framework, user can use this function with
v4l2 ioctl interface.
User send the output and capture buffer to driver and
driver store the converted data to the capture buffer.
This feature can be shared by ASRC and EASRC drivers

Rob Herring has complained about this section of code. I removed the
command line handling code to the cmdline.h header. This hopefully makes
it easier for Rob to maintain it (at least he doesn't have to look at it
directly anymore). I would like to add a Kconfig option called
OF_DEPRECATED_CMDLINE
This updates the x86 code to use the CONFIG_GENERIC_CMDLINE
option.

This updates the mips code to use the CONFIG_GENERIC_CMDLINE
option.
This deletes the option for MIPS_CMDLINE_BUILTIN_EXTEND
and replaces the functionality with generic code.
Of note, the pic32 has some strange handling of the current built
in command line. It was converted to use the static vari
This removes arm64 from the device tree handling of the
command line arguments.
The boot_command_line variable is populated inside the earliest
user of the command line, which is in idreg-override.c.
The device tree should not be needed to do any further handling
of the boot command line options.
This adds changes to the insert-sys-cert tool to allow updating
the cmdline_prepend and cmdline_append symbols in addition to
adding certificates.
Updating the cmdline symbols was tested on a PVH virtual machine
with a vmlinux, and with a bzImage which was repackaged on x86.
This commit intention
This adds code to handle the generic command line changes.
The efi code appears that it doesn't benefit as much from this design
as it could.
For example, if you had a prepend command line with "nokaslr" then
you might be helpful to re-enable it in the boot loader or dts,
but there appears to be n
Since the tool is used to update the command line and/or
to update the certificates, I think it makes sense to
changes the name of this tool.
Update the name of the tool to better reflect it's new use.

This code allows architectures to use a generic builtin command line.
The state of the builtin command line options across architecture is
