This patchset introduces Axiado SoC AX3000 and a EVK SCM3003 for emulation
The model for Axiado SoC AX3000 supports
  4 Cortex-A53 CPUs
  Arm Generic Interrupt Controller v3
  4 Cadence UARTs
  1 SDHCI controller with PHY
  8 Cadence GPIOs

Verified the machine "axiado-scm3003" with following command

qemu-system-aarch64 \
    -m 4G \
    -machine axiado-scm3003 \
    -device loader,file=u-boot.bin,addr=0x3C000000,cpu-num=0 \
    -nographic \
    -serial null \
    -serial null \
    -serial null \
    -serial mon:stdio \
    -drive if=sd,file=obmc-phosphor-image-evk-axiado-qemu.wic,format=raw

Changes in v3:
  1. Add a new patch for Axiado SD host controller
  2. Fill in valid/impl parameters of MemoryRegionOps in
     ax3000-soc/cadence_gpio/axiado_sdhci
  3. Follow C99 standard to declare variable in for-loop
  4. Remove comment "TBD" from empty function
  5. Define marco for bit definition in axiado_sdhci
  6. Move object_initialize_child() to instance_init() from realize() in
     axiado_sdhci
  7. Remove callback of get_default_cpu_type() from ax3000-soc and set
     type of CPU to A53
  8. Update the command to run "axiado-scm3003" in QEMU 

Changes in v2:
  1. Move axiado-* to ax3000-* in hw/arm and include/hw/arm
  2. Add axiado_sdhci to support AXIADO_SDHCI
  3. Move implementation for eMMC PHY device to axiado_sdhci
  4. Use UNIMP to create dummy device "timerctrl"
  5. Add cadence_gpio to support CADENCE_GPIO
  6. Enable Cadence GPIO controllers on AX3000 SoC
