V2: - Replace shmobile with dts since it's a DT patch in subject
    - Connect the 9063_IRQ# line to GP3_31
    - Since the DA9063 is connected to both i2c1 and i2c7, connect
      it to i2c7, which is the dedicated dvfs i2c.

Given Silk has the full da9063 (unlike the "L" version on Porter), shouldn't
you add an rtc subnode?

Oh, Silk also has the onkey pin wired, so perhaps you want to add an onkey
subnode, too? Does that feature work?

BTW, Stout also has the onkey wired, but lacks the onkey subnode.
