The driver relies on the reset controller API to work, so add
RESET_CONTROLLER as one of its Kconfig dependencies.
It also selects PHY_SUN6I_MIPI_DPHY, which depends on RESET_CONTROLLER.

PHY_SUN6I_MIPI_DPHY is not a freely selectable option and so may not
always be available. Depend on it instead.

The sun6i-mipi-csi2 and sun6i-a83t-mipi-csi2 drivers depend on the generic
MIPI D-PHY support. Select it. This fixes a linking problem when either of
these drivers is enabled and GENERIC_PHY_MIPI_DPHY is disabled.

The A31 MIPI CSI-2 controller is a dedicated MIPI CSI-2 bridge
found on Allwinner SoCs such as the A31 and V3/V3s.
It is a standalone block, connected to the CSI controller on one side
and to the MIPI D-PHY block on the other. It has a dedicated address
space, interrupt line and clock.
It is represented as a V4L2 subdev to the CSI controller and takes a
MIPI CSI-2 sensor as its own subdev, all using the fwnode graph and
media controller API.
Only 8-bit and 10-bit Bayer formats are currently supported.
While up to 4 internal channels to the CSI controller exist, only one
is currently supported by this implementation.
