Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20210129-1' into staging
target-arm queue:
 * Implement ID_PFR2
 * Conditionalize DBGDIDR
 * rename xlnx-zcu102.canbusN properties
 * provide powerdown/reset mechanism for secure firmware on 'virt' board
 * hw/misc: Fix arith overflow in NPCM7XX PWM module
 * target/arm: Replace magic value by MMU_DATA_LOAD definition
 * configure: fix preadv errors on Catalina macOS with new XCode
 * Various configure and other cleanups in preparation for iOS support
 * hvf: Add hypervisor entitlement to output binaries (needed for Big Sur)
 * Implement pvpanic-pci device
 * Convert the CMSDK timer devices to the Clock framework
