As we're starting from scratch (LA.UM.8.6.r1-04400-89xx.0), we need to add support for santoni again.

Initial support for Santoni, DTS included, Fixed Compilation.

• Added DTS file msm8950-pmi8950-qrd-sku7.dts
• Added santoni_defconfig
• Fixed DTB compilation (using -L to include soft links)
• Included own build.sh script
• Fixed missing/wrong file paths (instead of directly editing includes, remember to edit each makefile as needed) Not needed, fixed by adding O=out to all make calls.

Feature: Touchscreen FT5336

• Modified our DTS to match attributes of generic touch panel driver.
• Included logic to search for the correct memory register of our TP.
