m68k/atari: Avoid VLA use in atari_switches_setup()
With gcc 7.3.0: arch/m68k/atari/config.c: In function ‘atari_switches_setup’: arch/m68k/atari/config.c:151:2: warning: ISO C90 forbids variable length array ‘switches’ [-Wvla] char switches[strlen(str) + 1]; ^~~~ Replace the variable size by the maximum kernel command line size (256 bytes), which is an upper limit for all suboptions.
