* Raw NAND

The most meaningful change being the conversion of the brcmnand driver
to the ->exec_op() API, this series brought additional changes to the
core in order to help controller drivers to handle themselves the WP pin
during destructive operations when relevant.

As always, there is as well a whole bunch of miscellaneous W=1 fixes,
together with a few runtime fixes (double free, timeout value, OOB
layout, missing register initialization) and the usual load of remove
callbacks turned into void (which led to switch the txx9ndfmc driver to
use module_platform_driver()).
