m68k: atari: Add and use "atari.h"
When building with W=1: arch/m68k/atari/time.c:59:1: warning: no previous prototype for ‘atari_sched_init’ [-Wmissing-prototypes] 59 | atari_sched_init(void) | ^~~~~~~~~~~~~~~~ arch/m68k/atari/time.c:140:5: warning: no previous prototype for ‘atari_mste_hwclk’ [-Wmissing-prototypes] 140 | int atari_mste_hwclk( int op, struct rtc_time *t ) | ^~~~~~~~~~~~~~~~ arch/m68k/atari/time.c:199:5: warning: no previous prototype for ‘atari_tt_hwclk’ [-Wmissing-prototypes] 199 | int atari_tt_hwclk( int op, struct rtc_time *t ) | ^~~~~~~~~~~~~~ arch/m68k/atari/ataints.c:267:13: warning: no previous prototype for ‘atari_init_IRQ’ [-Wmissing-prototypes] 267 | void __init atari_init_IRQ(void) | ^~~~~~~~~~~~~~ arch/m68k/atari/atasound.c:36:6: warning: no previous prototype for ‘atari_microwire_cmd’ [-Wmissing-prototypes] 36 | void atari_microwire_cmd (int cmd) | ^~~~~~~~~~~~~~~~~~~ arch/m68k/atari/atasound.c:53:6: warning: no previous prototype for ‘atari_mksound’ [-Wmissing-prototypes] 53 | void atari_mksound (unsigned int hz, unsigned int ticks) | ^~~~~~~~~~~~~ Fix this by introducing a new header file "atari.h" for holding the prototypes of functions implemented in arch/m68k/atari/.
