Port EdkUnixPkg to UnixPkg. The changes are listed as follows:
1. change *.msa to *.inf, and create platform configuration files .dec&.dsc&.fdf to comply with Edk2 build process
2. using PCD mechanism to replace macro.
3. change Sec code to cowork with PI1.0 Pei Core and produce temparory memory ppi.

+ Routine Description:
+ Allows the user to set controller specific options for a controller that a
+ driver is currently managing.
+
+ Arguments:
+ This - A pointer to the EFI_DRIVER_CONFIGURATION_ PROTOCOL instance.
+ ControllerHandle - The handle of the controller to set options on.
+ ChildHandle - The handle of the child controller to set options on. This
+ is an optional parameter that may be NULL. It will be NULL
+ for device drivers, and for a bus drivers that wish to set
+ options for the bus controller. It will not be NULL for a
+ bus driver that wishes to set options for one of its child
+ controllers.
+ Language - A pointer to a three character ISO 639-2 language identifier.
+ This is the language of the user interface that should be
+ presented to the user, and it must match one of the languages
+ specified in SupportedLanguages. The number of languages
+ supported by a driver is up to the driver writer.
+ ActionRequired - A pointer to the action that the calling agent is required
+ to perform when this function returns. See "Related
+ Definitions" for a list of the actions that the calling
+ agent is required to perform prior to accessing
+ ControllerHandle again.
+
+ Returns:
+ EFI_SUCCESS - The driver specified by This successfully set the
+ configuration options for the controller specified
+ by ControllerHandle..
+ EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
+ EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.
+ EFI_INVALID_PARAMETER - ActionRequired is NULL.
+ EFI_UNSUPPORTED - The driver specified by This does not support setting
+ configuration options for the controller specified by
+ ControllerHandle and ChildHandle.
+ EFI_UNSUPPORTED - The driver specified by This does not support the
+ language specified by Language.
+ EFI_DEVICE_ERROR - A device error occurred while attempt to set the
+ configuration options for the controller specified
+ by ControllerHandle and ChildHandle.
+ EFI_OUT_RESOURCES - There are not enough resources available to set the
+ configuration options for the controller specified
+ by ControllerHandle and ChildHandle.
