[PATCH AUTOSEL 5.15 11/21] m68knommu: fix non-specific 68328 choice interrupt build failure

[Sasha Levin]

From: Greg Ungerer <gerg@linux-m68k.org>

[ Upstream commit 750321ace9107e103f254bf46900629ff347eb7b ]

Compiling for a classic m68k non-MMU target with no specific CPU
selected fails with the following error:

   arch/m68k/68000/ints.c: In function 'process_int':
>> arch/m68k/68000/ints.c:82:30: error: 'ISR' undeclared (first use in this function)
      82 |         unsigned long pend = ISR;
         |                              ^~~

This interrupt handling code is specific to the 68328 family of 68000
parts. There is a couple of variants (68EZ328, 68VZ328) and the common
ancestor of them the strait 68328.

The code here includes a specific header for each variant type. But if
none is selected then nothing is included to supply the appropriate
register and bit flags defines.

Rearrange the includes so that at least one type is always included.
At the very least the 68328 base type should be the fallback, so make
that true.

[PATCH AUTOSEL 5.15 12/21] m68knommu: fix non-mmu classic 68000 legacy timer tick selection

[Sasha Levin]

From: Greg Ungerer <gerg@linux-m68k.org>

[ Upstream commit 18011e50c497f04a57a8e00122906f04922b30b4 ]

The family of classic 68000 parts supported when in non-mmu mode all
currently use the legacy timer support. Move the selection of that config
option, LEGACY_TIMER_TICK, into the core CPU configuration.

This fixes compilation if no specific CPU variant is selected, since
the LEGACY_TIMER_TICK option was only selected in the specific CPU
variant configurations.
