target/xtensa: import core lx106
This is the core used in e.g. ESP8266 chips. Importing them
using import_core.sh, with the required files sourced from
https://github.com/espressif/xtensa-overlays
core-lx106.c was generated by the script; the only change is removing
the reference to core-matmap.h which doesn't seem to be available.
