This is the command infrastructure for the CC33xx.
Similar to wlcore, all commands eventually reach
__cc33xx_cmd_send which fills a generic command
header and send the buffer via the IO abstraction layer.
Unlike wlcore, there is no polling for command completion
which is received via an interrupt which signals
cc->command_complete.
