Try fix flash restrictions for W600 and W800 (#1936)

* Try fix flash restrictions for W600 and W800 by moving start of FLASH_VARS (changing FLASH_VARS_STRUCTURE_ADDR)
So restrictions in new_pins.h should be obsolete (allowing e.g. second SSID for W600 and W800)
For W800 restriction should be no longer present since some time, because it was moved to easyflash some time ago...

* Fix code in new_cfg.c, too

Removed special handling for W600 and updated config version.

* Tried an "update" mechanism: move flash_vars to new location if config is version 3

* Fix overwriting configSize in CFG_CalcChecksum() in case of V3 config

* I try fixing error for XR platforms for conflicting SSD1306_Init by excluding local "components" dir

* Try fixig build by removing "-lcomponent"

* Try fix for XR806, too

* try zeroing new space in config

* Try fixing zero memory
Add some more debug output

* Removed test code for fixing XRadio devices - nothing to do with this PR
Removed debug output

* Change to reflect moving flashvars from local structure to easyflash in latest commit
