Merge remote-tracking branches 'ras/edac-amd-atl', 'ras/edac-misc' and 'ras/edac-drivers' into edac-updates

* ras/edac-amd-atl:
  RAS/AMD/ATL: Translate normalized to system physical addresses using PRM
  ACPI: PRM: Add PRM handler direct call support

* ras/edac-misc:
  EDAC/synopsys: Fix error injection on Zynq UltraScale+

* ras/edac-drivers:
  EDAC: Drop obsolete PPC4xx driver
  EDAC/sb_edac: Fix the compile warning of large frame size
  EDAC/{skx_common,i10nm}: Remove the AMAP register for determing DDR5
  EDAC/{skx_common,skx,i10nm}: Move the common debug code to skx_common
  EDAC/igen6: Fix conversion of system address to physical memory address
