chuwi-hi10plus: new device (CHUWI Hi10 Plus) (!347)

This port uses the Android bootloader (kernelflinger) instead of
Gummiboot or rEFInd,... just in case if people still want to easily
reflash Android later without going through some DNX Fastboot, Intel
Flash Tool blah blah.

Chuwi violates GPLv2 by not releasing the kernel sources of Android to
the public. This port uses Linux mainline (5.1-rc7), and almost
everything works properly, so thankfully we don't have to use the 3.10
kernel which is outdated and EOL.

[ci:skip-build]: kernel takes more than an hour to compile on CI.
                 ollieparanoid made sure that everything builds.
