Add a send/notify abstraction for the mailbox and separate the message
handling in the driver from the code to read and write message to the
mailbox.
This untangles how mails are written into the MCU's SRAM and signaled to
the MCU from the protocol between the driver and the firmware.

Rework the functions that read and write the SRAM that is used to
communicate with the MCU.
As the functions will not operate on structs but on prepared binary
buffers, make the buffer stride more explicit. Also, avoid any uses of
struct mcu_msg_header to analyze messages in memory, because the header
will be made independent of the binary representation in the mailbox.
Instead explicitly access the mail size field in the mailbox.
As at it, further reduce the dependency between the mailboxes and struct
allegro_dev.

The message format in the mailboxes differ between firmware versions.
Therefore, it is necessary to decouple the mailbox format of the driver
from the message format of the firmware. This allows to keep a
consistent message format in the driver while still supporting various
firmware versions.
Add an intermediate step to encode and decode message before writing the
mails to the mailboxes.
On the other hand, this allows to handle optional fields in the
messages, which is required for advanced features of the encoder and was
not possible until now.

When pushing the buffers for the intermediate and reference frames to
the MCU, the driver relied on the message size to calculate the number
of buffers. As it is not necessary anymore to keep the messages binary
compatible to the firmware, we can just explicitly write the number of
buffers into the message.

The messages are now explicitly converted from the struct to the binary
representation used by the firmware. Therefore, there is no need to keep
the structs packed anymore.
Drop the attribute and avoid confusion why the mails are packed.

Like the message format, also the identifiers in the messages differ
between firmware versions. This especially affects the identifier for
the codec that shall be used. As the messages used by the driver are now
independent from the firmware, we can use the values defined by V4L2 as
identifiers in the messages.
Convert the V4L2 codec format to the respective firmware value when
encoding the messages to binary format instead beforehand.

Even bits in bitfields do not keep their position, but move around or
move to other bitfields. Therefore, the driver has to handle bitfields
differently depending on the firmware version.
Create separate fields for the options that have been in bitfields and
handle the bitfields when encoding the message.
As a side effect, this makes the messages a bit more readable.

Firmware versions >= 2019.2 do not configure the channel via the mailbox
interface anymore, but use a separate chunk of memory that is only
referenced by the message. As the configuration must be in a format that
is understood by the firmware and this format can change between
firmware versions, handle it similar to the message and treat is as a
blob.
In order to support both methods in the driver, always use a separate
blob for the channel configuration and copy that blob into the mailbox
if the firmware requires it and otherwise reference it.

The firmware decides how many reference frames shall be used und returns
this information via the config blob. In order to set the number of
reference frames in the PPS, the driver has to read these values from
the config blob after the channel has been created in the firmware.

The length of the message will be determined when the message is
encoded. Writing the size of the struct into the message in the driver
won't be the actual length of the message that is send to the firmware.
Therefore, drop the length field from the message.
Since the header is the same for all response messages, it does not make
sense to read the header in each decoding function, but we can simply
decode it once before dispatching to the respective functions.

In order to distinguish the message format that is expected by the
firmware, add a version field to the message header. This allows to
encode and decode the messages for the version of the firmware that was
loaded by the driver.

Encode messages as necessary for the firmware 2019.2 and, thus, support
the more recent firmware version in the driver, too.
