CONFIG_PM is defined when CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME is defined,
however suspend and resume methods are only valid in the context of
CONFIG_PM_SLEEP. If only CONFIG_PM_RUNTIME is defined we get the following
warning (courtesy of Geerts randconfig builds):lm8323.c: warning: 'lm8323_resume' defined but not used

Sysfs attribute show methods are always passed a buffer of length
PAGE_SIZE. To keep from overwriting this buffer and causing havoc, use
snprintf() to guarantee we never write more than the buffer can hold.In addition, at least for my touchscreen, the number and size of objects
was far too big to fit in a single 4K page. Therefore, this patch also
trims some redundant framing text to leave more room for actual data.Signed-off-by: Daniel Kurtz

V2 hardware has many variants. This patch adddresses two issues:
- some model also has debounce packets, but with a different signature
than v3. Now we just check debounce for all v2 hardware.- due to different scanning methods the hardware uses, x and y ranges have
to be calculated differently. And for some specific versions, we can just
see them as custom-made, so set {x, y} the same values as Windows driver
does.Signed-off-by: JJ Ding
