[PATCH v2 8/8] mtd: rawnand: bcm47xx: Merge all source files

[Boris Brezillon <boris.brezillon@xxxxxxxxxxxxx>]

Given the number of lines it doesn't make sense to split the code.
Let's merge everything and move the driver to drivers/mtd/nand/raw.

Signed-off-by: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxx>
---
Changes in v2:
* Fix the Makefile entry
* Merge commits doing the source merge and the file move
* Rename the driver bcm47xx-nand-controller
