Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20200623' into staging

target-arm queue:
 * util/oslib-posix : qemu_init_exec_dir implementation for Mac
 * target/arm: Last parts of neon decodetree conversion
 * hw/arm/virt: Add 5.0 HW compat props
 * hw/watchdog/cmsdk-apb-watchdog: Add trace event for lock status
 * mps2: Add CMSDK APB watchdog, FPGAIO block, S2I devices and I2C devices
 * mps2: Add some unimplemented-device stubs for audio and GPIO
 * mps2-tz: Use the ARM SBCon two-wire serial bus interface
 * target/arm: Check supported KVM features globally (not per vCPU)
 * tests/qtest/arm-cpu-features: Add feature setting tests
 * arm/virt: Add memory hot remove support
