Support for RPI-RF-MOD/HM-MOD-RPI-PCB for HomeMatic/homematicIP communication (#1266)

Browse Source 
* add eq3_char_loop package (eQ-3 char loopback kernel module)

* add generic_raw_uart package (low-latency raw UART kernel driver)

* add rpi-rf-mod package 

* add device tree overlay support for RPI-RF-MOD/HM-MOD-RPI-PCB on Raspberry Pi

* enable GPIOLIB and GPIO_SYSFS required for RPI-RF-MOD/HM-MOD-RPI-PCB support.

* add basic RPI-RF-MOD/HM-MOD-RPI-PCB support for ASUS Tinker Board

* add device tree overlay support for ASUS Tinker Board and add
haos-config.txt loading support to U-Boot boot script
