Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20210702' into staging

target-arm queue:
 * more MVE instructions
 * hw/gpio/gpio_pwr: use shutdown function for reboot
 * target/arm: Check NaN mode before silencing NaN
 * tests: Boot and halt a Linux guest on the Raspberry Pi 2 machine
 * hw/arm: Add basic power management to raspi.
 * docs/system/arm: Add quanta-gbs-bmc, quanta-q7l1-bmc
