/** @file
This file also installs UEFI PLATFORM_DRIVER_OVERRIDE_PROTOCOL.
The main code offers a UI interface in device manager to let user configure
platform override protocol to override the default algorithm for matching
drivers to controllers.
The main flow:
1. It dynamically locates all controller device path.
2. It dynamically locates all drivers which support binding protocol.
3. It exports and dynamically updates two menu to let user select the
mapping between drivers to controllers.
4. It save all the mapping info in NV variables which will be consumed
by platform override protocol driver to publish the platform override protocol.
