Input: elan_i2c - add ASUS EeeBook X205TA special touchpad fw

commit 92ef6f97a66e580189a41a132d0f8a9f78d6ddce upstream.

EeeBook X205TA is yet another ASUS device with a special touchpad
firmware that needs to be accounted for during initialization, or
else the touchpad will go into an invalid state upon suspend/resume.
Adding the appropriate ic_type and product_id check fixes the problem.
