I am trying to install PCIe drivers in my Linux host machine and there is a compilation error when I run make install. It says implicit declaration of function "mmiowb()". I am using Linux version 5.3.0-28-generic.
Please let me know if there any fixes for this.

I ran into the same problem. Does the driver work correctly after you commented out the function call? That memory barrier is there for a reason. I wonder if there is any ill-effect if you just take it out.
