parentInput: add static inline accessors for ABS properties (diff)

Input: switch to input_abs_*() access functions
Change all call sites in drivers/input to not access the ABS axis information directly anymore. Make them use the access helpers instead. Also use input_set_abs_params() when possible. Did some code refactoring as I was on it. Signed-off-by: Daniel Mack <daniel@caiaq.de> Cc: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
