The bd622663192e8ebebb27dc1d9397f352a82d2495 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.
