* @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 expressed as a hard-coded decimal integer literal without leading
* zeroes (e.g. 32); symbolic expressions are not permitted.
* 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).
