include/efi: Clean up efi_datatype.h file

This patch cleans up `efi_datatype.h` to allow other SoC and/or driver
code to use this file.

`PiPei.h` file only gets added from UDK2017 hence, the platform with the
older EDK2 base (prior to UDK2017) is unable to resolve this file
dependency.

This CL removed the `PiPei.h` header and only added the required header
file `PiPeiCis.h` for platforms with UDK base >= 2017.
