Subject: [PATCH][next] input: ti_am335x_tsc: remove redundant assignment to variable config

The variable config is being initialized with a value that is never
read, it is being re-assigned in the next statement. The initialization
is redundant and can be removed.

Cleans up clang scan build warning:
drivers/input/touchscreen/ti_am335x_tsc.c:160:2: warning: Value stored
to 'config' is never read [deadcode.DeadStores]
