UPSTREAM: mtd: nand: raw: Fix CONFIG_SYS_NAND_DRIVER_ECC_LAYOUT behavior

The purpose of "mtd: nand: raw: allow to disable unneeded ECC layouts"
was to allow disabling the default ECC layouts if a driver is known to
provide its own ECC layout. However, this commit did the opposite and
disabled the default layout when it was _not_ selected.

It breaks all the NAND drivers not providing their own ECC layout this
patch fix this situation.

It was tested with the lpc32xx_nand_slc driver.

UPSTREAM: mtd: nand: provide several helpers to do common NAND operations

Linux commit 97d90da8a88 ("mtd: nand: provide several helpers
to do common NAND operations")

This is part of the process of removing direct calls to ->cmdfunc()
outside of the core in order to introduce a better interface to execute
NAND operations.

Here we provide several helpers and make use of them to remove all
direct calls to ->cmdfunc(). This way, we can easily modify those
helpers to make use of the new ->exec_op() interface when available.

UPSTREAM: mtd: move NAND files into a raw/ subdirectory

NAND flavors, like serial and parallel, have a lot in common and would
benefit to share code. Let's move raw (parallel) NAND specific code in a
raw/ subdirectory, to ease the addition of a core file in nand/ and the
introduction of a spi/ subdirectory specific to SPI NANDs.
