[llvm] [M68k] Use M68010 cpu as target for SR move test (PR #122452)

[Janis Heims via llvm-commits]

https://github.com/TechnoElf created https://github.com/llvm/llvm-project/pull/122452

Fixes the test introduced in #111145.

It would also make sense to throw an error when the user attempts to use a move-from-sr on an unsupported architecture. Currently the encoder generates garbage instructions for a 68000 because the AsmMatcher is able to match the move against a MOV16rr:

```
> llvm-mc -triple=m68k -mcpu=M68000 -show-encoding MxMoveSR.s --debug
...
Trying to match opcode MOV16ar
  Matching formal operand class MCK_Reg against actual operand at index 1 (%7): match success using generic matcher
  Matching formal operand class MCK_AReg against actual operand at index 2 (%25): Opcode result: multiple operand mismatches, ignoring this opcode
Trying to match opcode MOV16rr
  Matching formal operand class MCK_Reg against actual operand at index 1 (%7): match success using generic matcher
  Matching formal operand class MCK_Reg against actual operand at index 2 (%25): match success using generic matcher
  Matching formal operand class InvalidMatchClass against actual operand at index 3: actual operand index out of range
Opcode result: complete match, selecting this opcode
EncodeInstruction: MOV16rr(901)
        move.w  %sr, %d1                        ; encoding: [0x32,0x00]
```

I haven't found a solution for this yet, so any ideas you have would be greatly appreciated.
