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.

a. Add check validation of RemainingDevicePath in Supported()
b. In Star() function, if RemaingDevicePath is the End of Device Path Node, don't create child device and return EFI_SUCCESS.
2. fixed one device path issue in ScsiBus driver.

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)

2. Update DxeIpl PEIM to not use S3Lib and RecoveryLib since the dependent PPIs have been moved from IntelFrameworkPkg to MdePkg. This will help to reduce the library instance selection in platform DSC files.

2. Simplify the implementation of PeiLoadImage() in PeiCore to skip the function call of PeiLoadImageLoadImage() because PeiCore itself produce one instance of EFI_PEI_LOAD_FILE_PPI.
