The regmap driver subsystem does not need any extra data, so it can use
`struct fdt_driver` directly. It always initializes the driver for a
specific DT node.

Since the FDT is not modified during driver initialization, node offsets
are just as suitable as phandles for use as identifiers: they are stable
and unique. With this change, it is no longer necessary to pass the
phandle to the driver init functions, so these init functions now use
the same prototype as other kinds of drivers.
This matches what is already done for I2C adapters.

Let us add a simple FDT based system regmap driver which follows the
device tree bindings already defined in the Linux kernel.
