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.
