Make some changes following Richard's advice based on version v1. And the
v1 patches fix some coverity errors and loongarch_cpu_class_by_name function
for LoongArch virt machine.

1. Use MAKE_64BIT_MASK(shift, len) to replace 'xxx << shift'.
2. Use ARRAY_SIZE(arrqy) to get the array size.
3. Add the assertion that 'cpu_model' resolve to a class of the
   appropriate type.
