Add Razer Blade Stealth (2016) H2U

The Razer Blade Stealth H2U is a KabyLake System using:
- Intel KBL 7500U
- ITE8528E SuperIO
- Intel 600P Series NVMe SSD
- Either four MT52L1G32D4PG (16GB) or MT52L512MB32D4PG (8GB)
  of soldered memory in dualchannel mode
- (Optional) Touchscreen
- HDMI 2.0a via DP-1: Paradetech PS175

Even tho it has a 16MB chip equipped (W25Q128.V) only the first 8MB
are used and mapped via IFD. The rest is left empty (0xFF). The flash is
not secured in any way and can be read via flashrom. It should be the
source for this port's IFD and ME blobs.

Working:
- USB-A Ports left and right
- Speakers
- Touchscreen (USB)
- Onboard Keyboard in Linux
- NVMe SSD
- SeaBIOS, Tianocore and Grub Payloads
- Webcam
- Powersaving Modes
- Battery state and LID switch, sometimes slow to update.
- Touchpad (I2C-HID)
- Headphones

Not part of this commit:
- Thunderbolt (Requires advanced EC signaling)
- Full HDMI support (Currently requires plugged connection at boot)
