When building with W=1:
arch/m68k/mm/hwtest.c:29:5: warning: no previous prototype for ‘hwreg_present’ [-Wmissing-prototypes]
29 | int hwreg_present(volatile void *regp)
| ^~~~~~~~~~~~~
arch/m68k/mm/hwtest.c:62:5: warning: no previous prototype for ‘hwreg_write’ [-Wmissing-prototypes]
62 | int hwreg_write(volatile void *regp, unsigned short val)
| ^~~~~~~~~~~
Fix this by including <asm/hwtest.h>.
