[PATCH] input: fix ucb1x00-ts breakage after conversion to dynamic input_dev allocation

Browse Source 
The bd62266319 commit broke the UCB1x00
touchscreen driver since the idev structure was assumed to be into the ts
structure, simply casting the former to the later in a couple places.

This patch fixes those, and also cache the idev pointer between multiple
calls to input_report_abs() to avoid growing the compiled code needlessly.
