Subject: [PATCH -next] m68k: mmu_context: Fix Sun-3 build

When building for Sun-3 (e.g. sun3_defconfig):

    In file included from ./arch/m68k/include/asm/mmu_context.h:312,
		     from arch/m68k/sun3/mmu_emu.c:28:
    ./include/asm-generic/mmu_context.h:46:20: error: redefinition of ‘destroy_context’
       46 | static inline void destroy_context(struct mm_struct *mm)
	  |                    ^~~~~~~~~~~~~~~
    In file included from arch/m68k/sun3/mmu_emu.c:28:
    ./arch/m68k/include/asm/mmu_context.h:192:20: note: previous definition of ‘destroy_context’ was here
      192 | static inline void destroy_context(struct mm_struct *mm)
	  |                    ^~~~~~~~~~~~~~~

Fix this by marking destroy_context implemented by arch-specific code.
