From: Gavin Shan <gshan@redhat.com>

It's found that some of the CPU type names in the array of valid
CPU types are invalid because their corresponding classes aren't
registered, as reported by Peter Maydell.

[gshan@gshan build]$ ./qemu-system-arm -machine virt -cpu cortex-a9
qemu-system-arm: Invalid CPU model: cortex-a9
The valid models are: cortex-a7, cortex-a15, (null), (null), (null),
(null), (null), (null), (null), (null), (null), (null), (null), max

Fix it by consolidating the array of valid CPU types. After it's
applied, we have the following output when TCG is enabled.

[gshan@gshan build]$ ./qemu-system-arm -machine virt -cpu cortex-a9
qemu-system-arm: Invalid CPU model: cortex-a9
The valid models are: cortex-a7, cortex-a15, max

[gshan@gshan build]$ ./qemu-system-aarch64 -machine virt -cpu cortex-a9
qemu-system-aarch64: Invalid CPU model: cortex-a9
The valid models are: cortex-a7, cortex-a15, cortex-a35, cortex-a55,
cortex-a72, cortex-a76, cortex-a710, a64fx, neoverse-n1, neoverse-v1,
neoverse-n2, cortex-a53, cortex-a57, max
