/** @def DEVICE_DEFINE
*
* @brief Define device object
*
* @details This macro defines a device object that is automatically
* configured by the kernel during system initialization.
*
* @param name Device name.
*
* @param data Pointer to the device's configuration data.
* @sa DEVICE_INIT_CONFIG_DEFINE()
*
* @param level The initialization level at which configuration occurs.
* Must be one of the following symbols, which are listed in the order
* they are performed by the kernel:
*
* PRIMARY: Used for devices that have no dependencies, such as those
* that rely solely on hardware present in the processor/SOC. These devices
* cannot use any kernel services during configuration, since they are not
* yet available.
*
* SECONDARY: Used for devices that rely on the initialization of devices
* initialized as part of the PRIMARY level. These devices cannot use any
* kernel services during configuration, since they are not yet available.
*
* NANOKERNEL: Used for devices that require nanokernel services during
* configuration.
*
* MICROKERNEL: Used for devices that require microkernel services during
* configuration.
*
* APPLICATION: Used for application components (i.e. non-kernel components)
* that need automatic configuration. These devices can use all services
* provided by the kernel during configuration.
*
* @param priority The initialization priority of the device, relative to
* other devices of the same initialization level. Specified as an integer
* value in the range 0 to 99; lower values indicate earlier initialization.
* Must be a decimal integer literal without leading zeroes or sign (e.g. 32),
* or an equivalent symbolic name (e.g. #define MY_INIT_PRIO 32); symbolic
* expressions are *not* permitted
* (e.g. CONFIG_KERNEL_INIT_PRIORITY_DEFAULT + 5).
