The bindings were added before the clock driver was properly mainlined and at first the clock driver was using ralink architecture dependent operations rt_memc_* defined in 'arch/mips/include/asm/mach-ralink/ralink_regs.h'. This string is already there on the memory controller node on mt7621.dtsi. Add syscon as a constant string on the compatible property, now that memc became a syscon. Update the example accordingly.
