Add udev rules and scripts for demo platform configurationicefish_8.99.3icefish/8.99.38.99.3
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.
