Add udev rules and scripts for demo platform configuration
Add recipes for udev rules and associated scripts 1) Support USB attached I2C devices for RTC and HVAC LED support. The RTC support loads and configures the required rtc-ds1307 driver, and sets the time from the RTC clock. The HVAC LED support configures the LED device names for use by the HVAC binding. The new demo-i2c-udev-conf recipe is added to DEMO_PLATFORM_CONF variable in packagegroup-agl-demo-platform to have them added to the agl-demo-platform image. Since they use udev rules to detect the corresponding hardware, this should be safe for all platforms.
