[PATCH 05/15] hw/alpha/typhoon: Create instance_init and class_init

[Yodel Eldar <yodel.eldar@yodel.dev>]

Define the Typhoon class and instance initializers.

Add "cpu[*]" link properties in the instance_init of Typhoon.
Setting these cpu link properties will occur in a later commit.

Note: This is one step towards splitting typhoon_init() into the
instance_init and realize hooks. typhoon_init() currently takes
a fixed cpus array as a parameter; that array will be removed soon.
