Add support for SONY Xperia XZ2, XZ2 Compact and XZ3 smartphones, all based on the Qualcomm SDM845 chipset. There also exists a fourth Tama device, the XZ2 Premium (Aurora) with a 4K display, but it's relatively rare.
The devices are affected by a scary UFS behaviour where sending a certain UFS command (which is worked around on downstream) renders the device unbootable, by effectively erasing the bootloader. Therefore UFS AND UFSPHY are strictly disabled for now.
Downstream workaround: https://github.com/kholk/kernel/commit/2e7a9ee1c91a016baa0b826a7752ec45663a0561
This platform's bootloader is not very nice either. To boot mainline you need to flash a bogus DTBO (fastboot erasing may cut it, but it takes an inhumane amount of time) - one that's just 4 bytes (all zeroes) seems to work just fine.
Of course, one can also provide a "normal" DTBO (device-specific DT overlayed on top of the SoC DT), but that's not yet supported by the mainline kernel build system.
