Prepare second set of changes for 3.6 merge window.

The touchpad on the Acer Aspire One D250 will report out of range values
in the extreme lower portion of the touchpad. These appear as abrupt
changes in the values reported by the hardware from very low values to
very high values, which can cause unexpected vertical jumps in the
position of the mouse pointer.

What seems to be happening is that the value is wrapping to a two's
compliment negative value of higher resolution than the 13-bit value
reported by the hardware, with the high-order bits being truncated. This
patch adds handling for these values by converting them to the
appropriate negative values.

The only tricky part about this is deciding when to treat a number as
negative. It stands to reason that if out of range values can be
reported on the low end then it could also happen on the high end, so
not all out of range values should be treated as negative. The approach
taken here is to split the difference between the maximum legitimate
value for the axis and the maximum possible value that the hardware can
report, treating values greater than this number as negative and all
other values as positive. This can be tweaked later if hardware is found
that operates outside of these parameters.

On some platform it may happen that the input clock to keyboard may
change during suspend, thus impacting its wakeup capability.

There is no means for keyboard driver to know this frequency before
hand. Hence introduce a platform data 'suspended_rate' which indicates
the frequency during suspend at which keyboard operates.

Accordingly reprogram keyboard while going into suspend and restore
original configuration at the time of resume.

envelope->attack_level is a u16 type.  We're trying to clamp it here
so it's between 0 and 0x7fff.  Unfortunately, the cast to __s16 turns
all the values larger than 0x7fff into negative numbers and min_t()
thinks they are less than 0x7fff.  envelope_level is an int so now
we've got negative values stored there.

Dmitry: I understand that I am a bit late to the party :) but I do not
agree with this change. Failure to create attributes is not sometihng
that user could cause (at least not easily) and thus would not be a
setup issue but something more severe. I believe we should fail
loading the driver so sysfs attribute breakage will be noticed as soon
as possible, instead of discovering it much much later in the process.

Since commit 1c6c6952 ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail. This patch adds the
IRQF_ONESHOT to input drivers where it is missing. Not modified by
this patch are those drivers where the requested IRQ will always be a
nested IRQ (e.g. because it's part of an MFD), since for this special
case IRQF_ONESHOT is not required to be specified when requesting the
IRQ.
