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.
