[S390] kernel: Storing machine flags early in lowcore
Currently, the machine_flags are stored late in the startup
initialization which results in failing machine type checks
(e.g. for MACHINE_IS_VM).
To allow these checks, store the machine flags in the lowcore
when the machine type has been detected.
Moving the machine_flags to the lowcore has been introduced with
