macintosh/mediabay: add a const qualifier

This prepares *of_device_id.data becoming const. Without this change
the following warning would occur:

	drivers/macintosh/mediabay.c: In function 'media_bay_attach':
	drivers/macintosh/mediabay.c:589:11: warning: assignment discards 'const' qualifier from pointer target type [enabled by default]
