platform: generic: Add an init hook matching fdt_driver

Browse Source 
In preparation for reusing the fdt_driver code to match platform
overrides, add a new .init hook matching the type signature from
fdt_driver. This hook replaces the existing .fw_init hook, since
it is called at roughly the same place in the init process.
