gpio: gpio-stmpe: make various char arrays static const, shrinks object size

Don't populate the read-only arrays edge_det_values, rise_values and
fall_values on the stack but instead make them static and constify them.
Makes the object code smaller by over 240 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
   9525	   2520	    192	  12237	   2fcd	drivers/gpio/gpio-stmpe.o

After:
   text	   data	    bss	    dec	    hex	filename
   9025	   2776	    192	  11993	   2ed9	drivers/gpio/gpio-stmpe.o
