This can help find unused symbols. Those end up without a type if
'default' is used instead of 'def_bool', which generates a warning.
Search for "Kconfig.defconfig" in
https://docs.zephyrproject.org/latest/application/kconfig-tips.html for
a longer explanation.
Keep the 'def_bool' for the following symbols, which seem to be
deliberately defined only in Kconfig.defconfig files:
- ALTERA_AVALON_I2C
- ALTERA_AVALON_MSGDMA
- ALTERA_AVALON_PIO
- ALTERA_AVALON_QSPI
- ALTERA_AVALON_SYSID
- CLOCK_CONTROL_IMX_CCM
- CPU_EM4_DMIPS
- CPU_EM4_FPUDA
- CPU_EM4_FPUS
- FP_FPU_DA
- I2C_GECKO

These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

All labels containing "_<8-hex-digits>_" or "16550_<3or6-hex-digits>_"
in their names, assumed to be generated by the extracting script,
are updated with the DT_ prefix, to reflect the recent changes made
to the script.

for socs which are using wdt qmsi driver.

The Zephyr configuration system uses many different files in many
different formats. It makes it a lot easier for users to understand
what these files do if when we use the correct file extensions.
To this end we rename the dts.fixup files to the correct file
extension '.h'.
This is a breaking change for out-of-tree fixup files. Such files will
be detected and given an appropriate error message.

Now that we get the spi base address and irq numbers from dts, we can
remove the preprocessor macros from soc.h

Makes the designware spi driver consistent with other spi drivers by
selecting HAS_DTS_SPI in the driver. This required adding spi nodes and
dts fixups to several arc and x86 socs, as well as enabling those nodes
in associated boards.
Also refactors the driver to use the base address, interrupt number, and
interrupt priority from dts.

Move the SoC outside of the architecture tree and put them at the same
level as boards and architectures allowing both SoCs and boards to be
maintained outside the tree.
