arm64: dts: exynos: gs101-pixel-common: add Maxim MAX77759 fuel gauge

Browse Source 
On Pixel 6 (and Pro), a MAX77759 companion PMIC for USB Type-C
applications is used, which contains four functional blocks (at
distinct I2C addresses):
  * top (including GPIO & NVMEM)
  * charger
  * fuel gauge
  * TCPCi

This change adds the fuel gauge.
