macintosh/adb: make adb_dev_class constant

Browse Source 
Since commit 43a7206b09 ("driver core: class: make class_register()
take a const *"), the driver core allows for struct class to be in
read-only memory, so move the adb_dev_class structure to be declared
at build time placing it into read-only memory, instead of having to
be dynamically allocated at boot time.
