spi: Extend the core to ease integration of SPI memory controllers

Some controllers are exposing high-level interfaces to access various
kind of SPI memories. Unfortunately they do not fit in the current
spi_controller model and usually have drivers placed in
drivers/mtd/spi-nor which are only supporting SPI NORs and not SPI
memories in general.

This is an attempt at defining a SPI memory interface which works for
all kinds of SPI memories (NORs, NANDs, SRAMs).

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

spi: Remove obsolete spi_base_setup_slave_fdt

0efc024 ("spi_flash: Add spi_flash_probe_fdt() to locate SPI by FDT
node") added a helper function spi_base_setup_slave_fdt to to set up a
SPI slave from a given FDT blob. The only user was the exynos SPI
driver.

But commit 73186c9 ("dm: exynos: Convert SPI to driver model") removed
the use of this function, hence rendering it obsolete.

Remove this function, as well as the CONFIG_OF_SPI option, which guarded
only this function.

For some SPI controllers it's not possible to keep the CS active between

This splits spi_flash reads into different iterations in order to respect

spi: Remove dual flash options/flags

Dual flash code in spi are usually take the spi controller
to work with dual connected flash devices. Usually these
dual connection operation's are referred to flash controller
protocol rather with spi controller protocol, these are still
present in flash side for the usage of spi-nor controllers.

So, this patch remove the dual_flash options or flags in sf
which are triggered from spi controller side.
