The manufacturer specific initialization has already been done when
block unlocking takes place, and if anything goes wrong during this
procedure we should call spinand_manufacturer_cleanup().

Looks like PROGRAM LOAD (AKA write cache) does not necessarily reset
the cache content to 0xFF (depends on vendor implementation), so we
must fill the page cache entirely even if we only want to program the
data portion of the page, otherwise we might corrupt the BBM or user
data previously programmed in OOB area.

W25N01GV is a single die version of the already supported
W25M02GV with half the capacity. Everything else is the
same so introduce support for W25N01GV.
Datasheet:http://www.winbond.com/resource-files/w25n01gv%20revl%20050918%20unsecured.pdf
Tested on 8devices Jalapeno dev board under OpenWrt running 4.19-rc5.

MX35LF2GE4AB is almost identical to MX35LF1GE4AB except it has 2 times
more eraseblocks per LUN and exposes 2 planes instead of 1.

Add a basic driver for Micron SPI NANDs. Only one device is supported
right now, but the driver will be extended to support more devices
afterwards.

Add a SPI NAND framework based on the generic NAND framework and the
spi-mem infrastructure.
In its current state, this framework supports the following features:
- single/dual/quad IO modes
- on-die ECC
