Samuel HollandandAnup Patel 1f8db2f18f lib: utils/regmap: Use fdt_driver for initialization 
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.

Anup PatelandAnup Patel 8e97275d97 lib: utils/regmap: Add simple FDT based regmap framework 
We add a simple FDT based regmap framework which is built on top of
generic regmap library. The phandle of FDT regmap DT node is treated
as unique regmap ID. The FDT based regmap drivers will be probed
on-demand from fdt_regmap_get_by_phandle() and fdt_regmap_get()
called by the regmap client drivers.
