Replace the FSF boilerplate with the SPDX tag.
The SPDX tag on files *.c is incorrect, as it should use the C99
single line comment using '//'. But current checkpatch doesn't
allow C99 comments, so keep using standard C comments, by now.

- write speed up to 150 kByte/s on STM32F469I-disco (due to
SWD clock and USB connection), up to 1 MByte/s on Nucleo-F767ZI
with external STLink-V3 or Nucleo-G474RE with two W25Q256FV in
dual 4-line mode or STM32H73BI-Disco in octal mode
- tested with STM32L476G-disco (64MBit flash, 3-byte addr),
STM32F412G-Disco, STM32F469I-Disco, STM32F746G-Disco, and
STM32L476G-Disco (all 128Mbit flash, 3-byte addr),
STM32F723E-Disco, STM32F769I-Disco (512Mbit flash, 4-byte addr)
STM32L4R9I-Disco, STM32L4P5G-Disco (512MBit octo-flash, DTR, 4-byte addr)
STM32H745I-Disco, STM32H747I-Disco (two 512MBit flash, 4-byte addr)
STM32H73BI-Disco, STM32H735G-Disco (512MBit octo-flash, DTR, 4-byte addr)
- suitable cfg for Discovery boards included
- limited parsing of SFDP data if flash device not hardcoded
(tested only in single/quad mode as most devices either don't
support SFDP at all or have empty(!) SFDP memory)
- 'set' command for auto detection override (e. g. for EEPROMs)
- 'cmd' command for arbitrary SPI commands (reconfiguration, testing etc.)
- makefile for creation of binary loader files
- tcl/board/stm32f469discovery.cfg superseded by stm32f469i-disco.cfg
- tcl/board/stm32f7discovery.cfg removed as name is ambiguous
(superseded by stm32f746g-disco.cfg vs. stm32f769i-disco.cfg)
- dual 4-line mode tested on Nucleo-F767ZI, Nucleo-H743ZI and Nucleo-H7A3ZI-Q
with two W25Q256FV, and on Nucleo-L496ZP-P and Nucleo-L4R5ZI
with two W25Q128FV, sample cfg files included and on STM32H745I-Disco,
STM32H747I-Disco, STM32H750B-Disco
- read/verify/erase_check uses indirect read mode to work around silicon bug in
H7, L4+ and MP1 memory mapped mode (last bytes not readable, accessing last
bytes causes debug interface to hang)
- octospi supported only in single/dual 1-line, 2-line, 4-line
and single 8-line modes, (not in hyper flash mode)
Requirements:
GPIOs must be initialized appropriately, and SPI flash chip be configured
appropriately (1-line ..., QPI, 4-byte addresses ...). This is board/chip
specific, cf. included cfg files. The driver infers most parameters from
current setting in CR, CCR, ... registers.

Use 'unsigned int' and 'bool' instead of 'int' where appropriate.
While at it, fix some coding style issues.
No new Clang analyzer warnings.

Final target is to force bus_width size during CFI flash
read.
In this first step I need to replace default flash read
with flash specific implementation.
This patch introduces:
- flash_driver_read() layer;
- default_flash_read(), backward compatible;
- read() callback in struct flash_driver;
- proper initialization in every flash_driver instance.

Move the bulk of the flash.h file into flash/nor/core.h, leaving an
empty husk that will be removed in the next patch.
The NOR driver structure is an implementation detail, so move it into
its own private header file <flash/nor/driver.h> along with helper
declaration for finding them by name.
Splits the exec mode commands out of flash.c into the flash/nor/ files.
The routines used by these high-level commands are moved into nor/core.c,
with their internal declarations placed in nor/imp.h.
Fixes distribution of <flash/nor/core.h> header.
The newly moved flash TCL routines access the internals of the module
too much. Fix the layering issues by adding new core NOR flash APIs:
<flash/nor/core.h>:
- flash_driver_find_by_name() - self-descriptive
<flash/nor/imp.h>:
- flash_bank_add() - encapsulates adding banks to bank list
- flash_bank_list() - encapsulates retreiving bank list
This allows the externs in flash/nor/imp.h to be removed, and
these mechanisms may now be re-used by other flash module code.
Moves the top-level 'flash' command handlers into flash/nor/tcl.c,
with flash/nor/imp.h providing an internal implementation header
to share non-public API components.
