Christian Borntraeger f5ae2a4fd8 s390/cpu: split CPU reset into architectured functions
s390 provides several CPU resets:
- CPU reset, clears interrupts, stop processing, clears TLB, but does
  not touch registers
- initial CPU reset, like CPU reset, but also clears PSW, prefix, FPC,
  timer and control registers. It does not touch gprs, fprs and acrs (!)
- Power on reset: the full monty

wire up CPUClass reset to the full monty, but provide the lesser resets
as part of S390CPUClass.
