[PATCH v5 3/3] ARM: bcm2835: Add DT for the firmware clocks driver.

[Eric Anholt]

Signed-off-by: Eric Anholt <eric@xxxxxxxxxx>
Acked-by: Lee Jones <lee@xxxxxxxxxx>
---

v2: Rename our compat string to mention bcm2835, and make our firmware
    phandle be under a vendor-namespaced property.

v3: Squashed in the patches to reference the other clocks, to avoid
    regressions now that we register all clocks at boot.  Dropped
    Stephen's ack, since he hadn't acked the new EMMC change yet.
