target-arm: Add virt class and machine types

Browse source 
Switch virt qemu machine support to use the newer object type, class, and
instance model. Added virt TypeInfo with static registration along with virt
specific class and machine structs. Also added virt class initialization
method.

Backports commit c29196904b2bad015edc553a5693c5c9e6f8177a from qemu
