ARM i.MX: Add driver to get sdram base and size
The code initializing the SDRAM controller is not at the same
place where SDRAM is registered with barebox. To reduce the
risk of registering wrong SDRAM sizes this patch adds a
driver for the ESDCTL which reads back the configured SDRAM
size and registers the memory found with barebox.
