the LASIPS2 device
When QOMifying a device it is typical to use _init() as the suffix for an
instance_init function, however this name is already in use by the legacy LASIPS2
wrapper function. Eventually the wrapper function will be removed, but for now
rename it to lasips2_initfn() to avoid a naming collision.
At the same time update lasips2_initfn() return the LASIPS2 device so that it
can later be accessed using qdev APIs by the HPPA machine.
