#I1X91O:如何用qemu运行系统内核，能给个教程吗？

### 原因（目的、解决的问题等）/ Cause (Purpose, Problem, etc.)

It would be nice to boot OpenHarmony in QEMU to allow development without hardware. This set of PRs adds BSP for a virtual Cortex-A7 boards, emulated by QEMU and a dedicated target for that board, so the output image can be ran on an emulated platform. At the moment only debug build is allowed, so OHOS boots to shell. There is no filesystem driver yet, so the only functionality available are commands embedded in shell.

### 描述（做了什么，变更了什么）/ Description (What Is Made and What Is Changed)

This PR alters some #include directives to fix compilation of non-HiSilicon targets, after the new QEMU target has been added.
