huawei-g7: new device (Huawei Ascend G7)

Administrator requested to merge huawei-g7 into master

The Huawei Ascend G7 is based on Qualcomm MSM8916 and therefore makes use of linux-postmarketos-qcom-msm8916 as a close-to-mainline kernel.

Initially supported features:

  • USB
  • Storage (eMMC, SD card)
  • Display
  • Touchscreen, Buttons, Vibrator
  • Notification LED
  • WiFi/Bluetooth
  • Accelerometer, Magnetometer, Proximity
  • Audio
  • NFC

The modem needs more work to work around strange Huawei firmware mess.

Note that the Huawei shipped an outdated firmware version that does not support booting aarch64 kernels (like used in this device port). However, the device does not verify firmware signatures so it is possible to flash firmware from other devices. This is mostly described in the wiki, but unfortunately it's quite complex.

However, the aarch64 version of linux-postmarketos-qcom-msm8916 receives much more testing so I would like to avoid adding more armv7 MSM8916 devices unless absolutely necessary.

For pointercal:

Screen dimension 720x1280
Touchscreen dimension (reported by evtest) 1100x1900
  720/1100*65536 = ~42896
  1280/1900*65536 = ~44151
Offset doesn't seem to be needed.
