This sequence should happen:
* CpuMp.c: Allocate a stack for the APs
* ApStartup.c: Send Start IPI to wake APs in 16-bit real mode
* MpAsm.S: AP enters CpuDxe driver code without stack
- AP grabs a lock
- AP sets up stack
- AP calls CpuMp.c:ApEntryPointInC

The AP startup code simply jumps into this code with the CpuDxe driver
without setting up a stack for the processor.
Therefore, this code must setup the stack before calling into C code.
This is the basic flow:
* AP enters CpuDxe driver code (AsmApEntryPoint) without stack
- AP grabs a lock
- AP sets up stack
- AP calls CpuMp.c:ApEntryPointInC
- If ApEntryPointInC returns, the lock is freed, and another AP may
run
- The AP C code may call AsmApDoneWithCommonStack to indicate that
the AP is no longer using the stack, and another may therefore
proceed to use the stack and then call ApEntryPointInC

This is the function the AP assembly code will expect to call after
getting a lock and setting up the stack.
Only one AP will enter this routine at a time.
If ApEntryPointInC exits, then the assembly code will loop around to
grab the lock, setup the stack, and call ApEntryPointInC again.
