The ad5791 currently assumes that the negative and positive supply have the
same absolute value, which is not necessarily true. This patch introduces a
offset attribute which will contain the negative supply voltage scaled
according to the iio spec. The raw attribute now accepts values in the range
of 0 to max instead of -max/2 to max/2.
While we are at it also fix the vref span calculation. Since both positive and
negative reference voltages are specificed as absolute values we need to add
them and not subtract them to get the reference voltage span.

Previously, the device-driver matching mechanism depended on the
vme_device_id structure due to the need for a bind table per driver.
This method of matching is no longer used so this patch merges the
fields of struct vme_device_id into struct vme_dev. Since this also
renders the slot field meaningless, it has also been removed in this
patch.

For jumper based boards (non VME64x), there is no mechanism
for detecting the card that is plugged into a specific slot. This
leads to issues in non-autodiscovery crates/cards when a card is
plugged into a slot that is "claimed" by a different driver. In
reality, there is no problem, but the driver rejects such a
configuration due to its dependence on the concept of slots.
This patch makes the concept of slots less critical and pushes the
driver match() to individual drivers (similar to what happens in the
ISA bus in driver/base/isa.c). This allows drivers to register the
number of devices that they expect without any restrictions. Devices
in this new model are now formatted as $driver_name-$bus_id.$device_id
(as compared to the earlier vme-$bus_id.$slot_number).
This model also makes the device model more logical as devices
are only registered when they actually exist whereas earlier,
a set of devices were being created automatically regardless of
them actually being there.
Another change introduced in this patch is that devices are now created
within the VME driver structure rather than in the VME bridge structure.
This way, things don't go haywire if the bridge driver is removed while
a driver is using it.

Instead of using a vanilla 'struct device' for VME devices, add new
'struct vme_dev'. Modifications have been made to the VME framework
API as well as all in-tree VME drivers.
The new vme_dev structure has the following advantages from the
current model used by the driver:
* Driver functions (probe, remove) now receive a VME device
instead of a pointer to the bridge device (cleaner design)
* It's easier to differenciate API calls as bridge-based or
device-based (ie. cleaner interface).

Note it is currently minimal in that there are no events and no

without messing up the clarity of what we have here.

zcache_do_preload() currently does a spin_trylock() on the
zcache_direct_reclaim_lock. Holding this lock intends to prevent
shrink_zcache_memory() from evicting zbud pages as a result
of a preload.
However, it also prevents two threads from
executing zcache_do_preload() at the same time. The first
thread will obtain the lock and the second thread's spin_trylock()
will fail (an aborted preload) causing the page to be either lost
(cleancache) or pushed out to the swap device (frontswap). It
also doesn't ensure that the call to shrink_zcache_memory() is
on the same thread as the call to zcache_do_preload().
Additional, there is no need for this mechanism because all
zcache_do_preload() calls that come down from cleancache already
have PF_MEMALLOC set in the process flags which prevents
direct reclaim in the memory manager. If the zcache_do_preload()
call is done from the frontswap path, we _want_ reclaim to be
done (which it isn't right now).
This patch removes the zcache_direct_reclaim_lock and related
statistics in zcache.
