media: allegro: add config blob for channel
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.
