Samsung DTS ARM changes for v6.9

Browse Source 
1. Disable thermal polling by Linux in Eynos5422 Odroid XU3 boards,
    because drivers implement now proper dynamic trip points management.
 
 2. Mark crosc-ec-spi in Peach Pi and Peach Pit as wake-up source, to
    reflect the hardware capabilities.
 
 3. Samsung P4 Note (Exynos4412): add accelerometer.
 
 4. Samsung Galaxy Tab (Exynos5420):
    - Reduce available RAM to avoid conflict with TrustZone.
    - Add WiFi on MMC.
