upxtreme: Add UP Xtreme support

Browse Source 
UP Xtreme is based on the Intel(R) Core(TM) i3/i5/i7 Whiskey Lake SoCs.
The UP Xtreme presents one Raspberry Pi compatible HAT connector.

This implementaion supports i2c, spi, uart, adc and gpio through the
40pin HAT connector.

Gpio chardev capabilities have been disabled in this implementation. When
gpio chardev capabilities are enabled an input becomes unreadable after an
isr has been registered to the pin. See here for details:

https://github.com/intel-iot-devkit/mraa/issues/937

Tested on UP Xtreme, with UP Board Linux kernel 5.0.0
Features tested: gpio, gpio interrupts, i2c, spi, adc and uart.
