To be clear, it's not that this hardware shouldn't be supported in the
SPI subsystem it's that if the driver is in the SPI subsystem it should
be written in terms of the relevant APIs.  Simply taking a MTD driver
and dropping it in a random other directory with no further updates
is clearly not the way forwards.

The patches should be individually standalone and useful, the problem
here is that it's difficult to review any of the patches by themselves
because they've not been split up with a clear goal.
