It turns out that v4's firmware provides a command so we can query
the resolution. Let's use it.

Starting with v3 hardware, the firmware supports this shorter
elantech_send_cmd. Teach the driver to use it.

With commit 67d0a0754455f89ef3946946159d8ec9e45ce33a we mark strict_strtox
as obsolete. Convert all remaining such uses in drivers/input/.

Also change long to appropriate types, and return error conditions
from kstrtox separately, as Dmitry sugguests.

This essentially reverts commit f81bc788ff91d4efd4baf88b2c29713838caa8e5.

With recent work on elantech driver, I believe we now have complete support
for all elantech touchpads. So remove this hack.

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.

v4 hardware is a true multitouch capable touchpad (up to 5 fingers).
The packet format is quite complex, please see protocol document for

v3 hardware's packet format is almost identical to v2 (one/three finger touch),
except when sensing two finger touch, the hardware sends 12 bytes of data.
