chromeos-bsp-daisy: create /dev/rtc symlink.

There are two viable PMIC options for the Exynos 5250: max77686 &
s5m8767.  Both contain RTCs that can be backed by battery/coin cell to
keep time across shutdowns.

CL includes those udev rules in one file.

BUG=chrome-os-partner:19036
TEST=manual,

  emerge-daisy chromeos-bsp-daisy
  emerge-daisy_spring chromeos-bsp-daisy
  USE=-snow emerge-daisy chromeos-bsp-daisy

All build successfully.  In the case of USE=-snow files are NOT installed.

Install file on Snow and Spring and reboot.  Then:
