The introduction commit 576d196c522b ("media: sunxi: Add support for the
A83T MIPI CSI-2 controller") says:

    This implementation splits the protocol and D-PHY registers and
    uses the PHY framework internally. The D-PHY is not registered as a
    standalone PHY driver since it cannot be used with any other
    controller.

However, this does not matter, and is not the only instance of tight PHY
provider <-> consumer pairing. According to Vinod Koul, having PHY
provider drivers outside of drivers/phy/ is discouraged, although it
would be difficult for me to address a proper movement here.

So just include the private provider API header from drivers/phy/ and
leave a FIXME in place.
