Make device tree pre-processing similar to U-boot/Linux
Following changes are done to make DT pre-processing similar to that of U-boot/Linux kernel. 1. Creating seperate CPPFLAGS for DT preprocessing so that compiler options specific to it can be accommodated. e.g: "-undef" compiler option avoids replacing "linux" string(used in device trees) with "1" as "linux" is a pre-defined macro in gnu99 standard. 2. Replace CPP with PP for DT pre-processing, as CPP in U-boot/Linux is exported as "${CROSS_COMPILE}gcc -E" while in TF-A it is exported as "${CROSS_COMPILE}cpp".
