m68k: atari: Rename shifter to shifter_st to avoid conflict

When test-compiling the BCM2835 pin control driver on m68k:

    arch/m68k/include/asm/atarihw.h:190:22: error: expected identifier or '(' before 'volatile'
     # define shifter ((*(volatile struct SHIFTER *)SHF_BAS))

"shifter" is a too generic name for a global definition.

As the corresponding definition for Atari TT is already called
"shifter_tt", fix this by renaming the definition for Atari ST to
"shifter_st".
