ArmPkg/BdsLib: Added support to change the given DevicePath of a Boot Entry
Some boot entries might not have a EFI Device Path FilePath
attached to it (eg: EFI device Path for removable device path).
This patch allows a support loader to edit the EFI Device Path
and for instance add \EFI\BOOT\BOOT(ARM|AA64).EFI
