ppc patch queue 2021-05-04

Browse source 
Here's the first ppc pull request for qemu-6.1.  It has a wide variety
 of stuff accumulated during the 6.0 freeze.  Highlights are:
 
  * Multi-phase reset cleanups for PAPR
  * Preliminary cleanups towards allowing !CONFIG_TCG for the ppc target
  * Cleanup of AIL logic and extension to POWER10
  * Further improvements to handling of hot unplug failures on PAPR
  * Allow much larger numbers of CPU on pseries
  * Support for the H_SCM_HEALTH hypercall
  * Add support for the Pegasos II board
  * Substantial cleanup to hflag handling
  * Assorted minor fixes and cleanups
