ARM: tegra: Add device-tree for ASUS Google Nexus 7 

There are few hardware variants of NVIDIA Tegra30-based Nexus 7 device:

1. WiFi-only (named Grouper)
2. GSM (named Tilapia)
3. Using Maxim PMIC (E1565 board ID)
4. Using Ti PMIC (PM269 board ID)

This patch adds device-trees for known and tested variants.
