platform/x86: asus-wmi: Move i8042 filter install to shared asus-wmi code

[ Upstream commit b52cbca22cbf6c9d2700c1e576d0ddcc670e49d5 ]

asus-nb-wmi calls i8042_install_filter() in some cases, but it never
calls i8042_remove_filter(). This means that a dangling pointer to
the filter function is left after rmmod leading to crashes.

Fix this by moving the i8042-filter installation to the shared
asus-wmi code and also remove it from the shared code on driver unbind.
