There is a move to deprecate bus-specific PM operations and move to
using dev_pm_ops instead in order to reduce the amount of boilerplate
code in buses and facilitiate updates to the PM core. Do this move for
the lis3lv02d SPI driver.

The interface is identical EMC6D102, so all that needs to be added are
some definitions and their uses.

Registers apparently missing in EMC6D103S/EMC6D103:A2 compared to EMC6D103:A0,
EMC6D103:A1, and EMC6D102 (according to the data sheets), but used
unconditionally in the driver: 62[5:7], 6D[0:7], and 6E[0:7]. For that
reason, EMC6D103S chips don't get enabled for the time being.

On systems where the temperature sensor is actually used, the BIOS is
likely to have locked the alarm registers.  In that case, all writes
through the corresponding sysfs files would be silently ignored.

To prevent this, detect the locks and make the affected sysfs files
read-only.

This is the same case as fschmd, from which the code was copied as far
as I can see. So the same clean-up applies:

The WDIOC_GETSUPPORT ioctl only needs a mutex because it operates on a
static variable. There is no good reason to keep this variable static,
so let's just make it non-static and drop the now useless mutex
altogether.

Functions set_fan_min() and set_fan_div() assume that the fan_div
values have already been read from the register. The driver currently
doesn't initialize them at load time, they are only set when function
via686a_update_device() is called. This means that set_fan_min() and
set_fan_div() misbehave if, for example, "sensors -s" is called
before any monitoring application (e.g. "sensors") is has been run.

Fix the problem by always initializing the fan_div values at device
bind time.

The code triggers a false warning with older versions of gcc:
w83795.c: In function 'w83795_update_device':
w83795.c:475: warning: 'lsb' may be used uninitialized in this function

I admit that the code is a little tricky, but I see no way to write it
differently without hurting performance. So let's just silent the
warning with a needless initialization.
