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.

Pull SCSI updates from James Bottomley:
"One new driver: leapraid (similar to mpi3mr but OK'd by Broadcom). The
usual suspects for driver updates (ufs, qla2xxx, smartpqi, zfcp, fnic,
ibmvfc) plus a few small core updates: a fix for an uninitialized sg
list pad bytes plus the removal of the dma mask check for max sectors.
The big update in the sd driver is mostly code refactoring for obscure
error leg handling"

<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:
$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038
The result is that even when touching an obscure device id struct most
of the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per subsystem
headers and only including what is really needed reduces the amount of
needed recompilation.
Implement the first step and define each device id struct in a separate
header (together with its associated #defines).
<linux/mod_devicetable.h> is modified to include all the new headers to
continue to provide the same symbols.
Several headers currently include <linux/mod_devicetable.h>, those that
are most lukrative to include only their subsystem headers only are:
$ git -C source grep -l mod_devicetable.h include/linux | while read h; do echo -n "$h:"; find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l $h | wc -l; done | sort -t: -k2 -n -r | head

struct cpu_feature isn't really a device_id struct. That is kept in
<linux/mod_devicetable.h> for now.
