Add device tree support for the Microsoft Lumia 950 smartphone. It is based on msm8992 and supports booting Linux via a custom EDK2 port. Currently it supports: * Screen console via EFIFB * Booting via EFI_STUB * SDHCI * I2C * PSCI core bringup Please note that there is an implementation of EL2 startup on this board, but it requires the user to resign from PSCI and use spin-table instead. This revision sticks with PSCI.
