Support Arduino Q (Qualcomm QRB2210 MPU part) #20
Description
Symmetric to platformio/platform-ststm32#869.
We need support for compiling, uploading and running native C/C++ programs to the Arduino Q (the Linux part of it).
The chip itself is a quad-core ARM Cortex-A53 (source, source), so supporting it in platform-linux_arm seems to make the most sense.
We need cross-compiling toolchains for all major OSes and a nice way to remote upload and execute via either pio remote or ssh.
