[PATCH v2 5/7] target/i386/cpu: Improve errors for out of bounds property values

[Markus Armbruster]

The error message for a "stepping" value that is out of bounds is a
bit odd:

    $ qemu-system-x86_64 -cpu qemu64,stepping=16
    qemu-system-x86_64: can't apply global qemu64-x86_64-cpu.stepping=16: 
Property .stepping doesn't take value 16 (minimum: 0, maximum: 15)

The "can't apply global" part is an unfortunate artifact of -cpu's
implementation.  Left for another day.

The remainder feels overly verbose.  Change it to

    qemu64-x86_64-cpu: can't apply global qemu64-x86_64-cpu.stepping=16: 
parameter 'stepping' can be at most 15

Likewise for "family", "model", and "tsc-frequency".
