This patch update the behavior introduced by
commit 96907c0fe5 ("dm: spi: Read default speed and mode values from DT")
In case of DT boot, don't read default speed and mode for SPI from
CONFIG_* but instead read from DT node. This will make sure that boards
with multiple SPI/QSPI controllers can be probed at different
bus frequencies and SPI modes.
Remove also use in boards of the value speed=0 (no more supported)
for ENV in SPI by using CONFIG_ENV_SPI_MAX_HZ=0.
DT values will be always used when available (full DM support of
SPI slave with available DT node) even if speed and mode are requested;
for example in splash screen support (in splash_sf_read_raw)
or in SPL boot (in spl_spi_load_image).
The caller of spi_get_bus_and_cs() no more need to force speed=0.
But the current behavior don't change if the SPI slave is not
present (device with generic driver is created automatically)
or if platdata is used (CONFIG_OF_PLATDATA).

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.

(cherry picked from commit a430fa06a4ac50e785fdbfb7f43c3cb14b35619c)
For the RK3399-Q7, we need some flexibility (depending on the feature
set we include in the SPL stage and how large our SPI flash is) in
positioning the SPL payload (i.e. the FIT image containing U-Boot, ATF
and the M0 payload) in our SPI flash.
To avoid having to deal with this through different U-Boot images, we
introduce a the '/config/u-boot,spl-payload-offset' property node
allow it to override the default setting.

It is useful to name each method so that we can print out this name when
using the method. Currently this happens using a separate function. In
preparation for unifying this, add a name to each method.
The name is only available if we have libcommon support (i.e can use
printf()).

Add check for FDT_MAGIC, otherwise also legacy images will be loaded as
a FIT. With this check in place, the loader works correct both
with legacy and FIT images.

Rather than having a global variable, pass the spl_image as a parameter.
This avoids BSS use, and makes it clearer what the function is actually
doing.

All the other SPL loaders are in this directory, so move the SPI one in
there too.
There are two board-specific SPI loaders (fsl and sunxi). These remain in
the drivers/mtd/spi directory, since they do not contain generic code.
