[PATCH v2] s390/ap: Drop unused member from ap_device_id

["Uwe Kleine-König (The Capable Hub)" <u.kleine-koenig@baylibre.com>]

ap_device_id::driver_info is not used in the kernel. The structure is
also not part of API/ABI, so the unused member can just be dropped.

Hello,

Sashiko was quick to identify two issues in my patch. Before someone
gets around to review v1 by hand, here is a v2 addressing Sashiko's
concerns:

 - remove the typedef for kernel_ulong_t
 - s/device_info/driver_info/ in the commit log

Thanks
Uwe
