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).

spi: Generalize SPI "master" to "controller"
Now struct spi_master is used for both SPI master and slave controllers,
it makes sense to rename it to struct spi_controller, and replace
"master" by "controller" where appropriate.
For now this conversion is done for SPI core infrastructure only.
Wrappers are provided for backwards compatibility, until all SPI drivers
have been converted.
Noteworthy details:
- SPI_MASTER_GPIO_SS is retained, as it only makes sense for SPI
master controllers,
- spi_busnum_to_master() is retained, as it looks up masters only,
- A new field spi_device.controller is added, but spi_device.master is
retained for compatibility (both are always initialized by
spi_alloc_device()),
- spi_flash_read() is used by SPI masters only.

The caam driver needs the variable habv4_need_rng_software_self_test,
but this is only declared when HABV4 is enabled. Instead of exporting
a variable rather provide a function to test if a software selftest
of the random number generator is needed.

When ramoops reserved a memory region in the kernel, it had an unhelpful
label of "persistent ram". When reading iomem, it would be repeated many
times, did not hint that it was ramoops in particular, and didn't
clarify very much about what each was used for:
0x4fdd4000 - 0x4fdf3fff (size 0x00020000) persistent ram
0x4fdf4000 - 0x4fe13fff (size 0x00020000) persistent ram
...
0x4ff74000 - 0x4ff93fff (size 0x00020000) persistent ram
0x4ff94000 - 0x4ffb3fff (size 0x00020000) persistent ram
0x4ffb4000 - 0x4ffd3fff (size 0x00020000) persistent ram
Instead, this adds meaningful labels for how the various regions are
being used:
0x4fdd4000 - 0x4fdf3fff (size 0x00020000) ramoops:dump(0/12)
0x4fdf4000 - 0x4fe13fff (size 0x00020000) ramoops:dump(1/12)
...
0x4ff74000 - 0x4ff93fff (size 0x00020000) ramoops:console
0x4ff94000 - 0x4ffb3fff (size 0x00020000) ramoops:ftrace

This adds the Freescale ddr driver used on various PowerPC and
Layerscape SoCs. This is based on U-Boot-2019.01 but with many
adjustments:
- PowerPC support has been removed
- CPP #ifdeffery replaced with C
- No more global variables/functions expected from the driver,
configuration is passed by the board code which calls the driver
We already have the driver in the tree in an older version forked from
U-Boot-2013.04. This version lacks Layerscape support and many quirks
in the driver are PowerPC specific. Since the existing driver should
work on all known PowerPC and PowerPC is a dead end I decided not to
improve the existing driver and instead add a new Layerscape specific
driver.

This adds ethernet support for the Freecale Layerscape SoCs. The
architecture in these SoCs is called "Data Path Acceleration
Architecture" (DPAA). It is comprised of:
- The Queue Manager (QMan)
- Buffer Manager (BMan)
- Frame Manager (FMan)
- Multirate Ethernet Media Access Controller (mEMAC)
The code is based on the corresponding U-Boot driver enriched with
device tree parsing and proper device driver support.
Tested on LS1046a, should work on other SoCs aswell with some minor
quirks. SerDes support has been removed for now.
