Hi All,

As this series only supports running binary files in ELF format, and
does not depend on BIOS and kernel file. so this series are changed from
RFC to patch vX.


The manual:
  - https://github.com/loongson/LoongArch-Documentation/releases/tag/2022.03.17

Old series:
  - https://patchew.org/QEMU/20220328125749.2918087-1-yangxiaojuan@loongson.cn/
  - https://patchew.org/QEMU/20220106094200.1801206-1-gaosong@loongson.cn/

This version we have done the following tests

configure with --enable-sanitizers

- make check  
   Ok:                 117
   Expected Fail:      0   
   Fail:               0
   Unexpected Pass:    0   
   Skipped:            2
   Timeout:            0
   
- make check-tcg

----

v7:
  - Rebase
  - Fixed extioi device emulation according to v6 advice.

v6:
  - Fixed ipi device check errors when enabled sanitizers. (patch 31)

  - Removed acpi device emulation temporarily, and replaced it with virt
power manager. (patch 40)

v5:
  - Fixed loongarch extioi device emulation.
  - Fixed loongarch rtc device emulation.
  - Fixed 'make docker-test-build' error.

v4:
  - Use 'la464' cpu type.
  - Fixed loongarch extioi device emulation.
  - Fixed loongarch rtc device emulation.
  - Fixed loongarch load elf function.

v3:
  - Add Check csr_names.
  - Drop CSR_CPUID, use cpu->cpu_index.
  - Fixed loongarch extioi device emulation. ipmap and coremap register
    change to 32bits.
  - Check_iocsr() function moved to loongarch_ipi_writel().
  - Pch_pic/msi use qdev_init_gpio_out() to init irq, and use
    qdev_connect_gpio_out() to connect irq.
  - Load elf function moved to hw/loongarch/loongson.c

v2:
  - Improvents to CSR/IOCSR instructions translation.
  - Fixed extioi device emulation. It is represented by only one memory
    region.
  - Fixed IPI device emulation. The registers are represented with
    uint64_t.
  - Use do_cpu_reset() and cpu_set_pc() to specify the load address.

v6: https://patchew.org/QEMU/20220601102509.985650-1-yangxiaojuan@loongson.cn/
