mb/razer: Add initial support for the Blade Stealth (late 2019) [ICL]

The Razer Blade Stealth Mercury White is a Ice Lake system using:
- Intel i7-1065G7 (Ice Lake with Iris Plus GPU)
- ITE IT8320VG EC (currently unsupported in coreboot)
- Samsung M981 MZ-VLKB2560 256GB NVMe SSD
- Four Samsung K4UBE3D4AM-GHCL LPDDR4 chips
- Integrated TitanRidge Thunderbolt 3 / 4 controller
- Two Realtek Audio chips:
  - ALC298 for the audio jack
  - ALC1306 for the speakers
- Parade PS8802 USB Type-C Host Switch
- Unlabeled Intel USB Type-C Thunderbolt Switch

This commit includes basic ram init and devicetree configuration
and therefore everything required to call into the payload.
It is missing ACPI, power and advanced device initialization
as well as EC support which should be included on its own in
a future commit.
