arm64: dts: qcom: sdm450: add Lenovo Smart Tab M10 DTS

This add initial support for the Lenovo Smart Tab M10 (WiFi)
(model tbx605f) which is a 10.1" tablet by Lenovo based on the
SDM450 SoC.

It has a 10.1" LCP touch panel, SDCard slot, Volume+Power buttons,
USB-C port amd front-facing camera (not supported).

The proper LCP Panel support will be added later, for now using the
simeple-framebuffer with the bootloader-initialized video memory.
