PcdFlashNvStorageFtwWorkingBase and PcdFlashNvStorageFtwSpareBase are
now updated each time an FVB instance is installed. This allows the
PCDs to be set at runtime at any time before the FVB is installed.

The others changes include:
a. Check RemainingDevicePath at beginning of Supported(), make sure it has been verified before Start() is called.
b. Check IO protocol firstly rather than EfiDevicePathProtocolGuid, reduce the times entering into Start() function because EfiDevicePathProtocolGuid existed on most of handle.
2. roll back serial drivers not to create child device, if the device speicifed by remainingdevicepath cannot find in the created devices list.

3. If no any child device is created on last time, and RemainingDevicePath is valid Uart Devcie path, go on creating child device handle based on this RemainingDevicePath.

Add PcdEmuVariableNvStoreReserved which allows a platform to declare a
memory address for the EMU Variable driver to use for the NV variable
store. The EMU Variable driver will look to see if the contents of
this memory range appear to be a valid variable store, and if so
the EMU driver will use the variables.
If a platform can preserve a memory range across system resets, this
feature can allow the EMU Variable driver's NV variable store to be
preserved across a system reset.
In the default case this PCD will be set as a fixed PCD with a value
of 0. In this case this new feature should have minimal impact on
the EMU Variable driver. (Perhaps a slight increase in code size,
but no functional difference is expected.)

1. Boot to shell
2. go to boot maint manager
3. Boot options
4. Add boot option
5. Add 15 or so unique boot options (just so the list scrolls)
6. go the boot maint manager
7. go to Boot options
8. go to Change boot order
9. the list is long enough that it scrolls when you push down once (to get to the commit option)
10. push down once and then up once (repeat) (from list selected to "commit" selected)
11. you will notice the list and text is getting corrupt
12. do it until all items in list are gone (system will assert)

This is a temporary fix that should for for most tool chains. A more complete fix will be required to guarantee compatibility with all tool chains.
