[PATCH 4/5 v2] ARM: kirkwood: convert rtc-mv to fdt.

[Jason Cooper]

The comment at mach-kirkwood/common.c:469, says this device is in every
kirkwood board.  So, it is placed in kirkwood.dtsi.

Signed-off-by: Jason Cooper <jason at lakedaemon.net>

Changes since v1:

    - removed unnecessary of_*() code from _probe()
    - use of_match_ptr()
