m68k: mm: Include <asm/hwtest.h> for hwreg_()

Browse Source 
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>.
