auxdisplay: ht16k33: Make ht16k33_fb_fix and ht16k33_fb_var constant
The static structures ht16k33_fb_fix and ht16k33_fb_var, of types fb_fix_screeninfo and fb_var_screeninfo respectively, are not used except to be copied into other variables. Hence make both of them constant to prevent unintended modification. Issue found with Coccinelle.
