Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
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

Iván Briano aba245daad drivers qmsi: Fix power management with reentrancy disabled
The new device control API added a 'device_power_state' variable to the
driver's data structure to keep track of the current power state set
for a device. This member variable is conditionally built into the
runtime data structure of each driver, but in some cases the whole data
structure is conditional on its respective API_REENTRANCY config
variable.

In those cases where the runtime data was previously used only for
reentrancy protection, the runtime data pointer used for device
initialization is NULL, and when power management is enabled, this
invalid pointer ends up dereferenced to get the device_power_state
member.

Make the declaration of the runtime data dependent on any of its
conditional members, and NULL only when all of those settings are
disabled.

Andre Guedes 3172fca3a0 drivers: qmsi: Fix gpio, i2c and wdt for D2000
This patch fixes the gpio, i2c and watchdog shim drivers so they set the
CLK_PERIPH_CLK bit during driver initialization. Differently from Quark
SE, the peripheral clock gate bit (CLK_PERIPH_CLK) is not enabled by
default in Quark D2000. We have to explicitly set this bit in order to
properly initialize the device.

This issue has been masked so far because the CLK_PERIPH_CLK bit is set
when UART NS16550 driver is enabled. The UART NS16550 driver is enabled
by default for Quark D2000 so gpio, i2c and watchdog sample apps were
working just fine. But if we disable the NS16550 driver, these samples
applications stop working.

The remaining shim drivers already set the CLK_PERIPH_CLK bit during
initialization so there is no need to fix them.

Andrew Boie d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.
