Martí Bolívar 6e8775ff84 devicetree: remove DT_HAS_NODE_STATUS_OKAY
Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:

- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
  for macros which are equivalent to
  DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name

Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.

This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Martí Bolívar 87e1743ae0 devicetree: replace DT_HAS_DRV_INST with DT_INST_FOREACH
Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.

There are a few exceptions:

- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
  would require more time to convert than I have at the moment. For the
  sake of expediency, just inline the DT_HAS_DRV_INST expansion for
  now in these cases.

- SoC drivers which are explicitly single-instance (like the nRF SAADC
  driver). Again for the sake of expediency, drop a BUILD_ASSERT in
  those cases to make sure the assumption that all supported SoCs have
  at most one available instance is valid, failing fast otherwise.

Leandro Pereira 158ea970ea drivers: watchdog: Use common name configuration for all drivers
Each driver seemed to use their own Kconfig option to set the name for
their drivers.  This makes writing example/test code difficult as each
one of them will have to special case for each of the supported
platforms.

Use a consistent CONFIG_WDT_0_NAME option in all drivers.

Fixes #8094.

Leandro Pereira d691045592 drivers: watchdog: Implement ESP32 watchdog driver
Zephyr's watchdog API is badly designed in the sense that it's a 1:1
abstraction on top of whatever Quark D2000 expects for its watchdog,
instead of expecting a generic timeout value.

This implementation tries as much as possible to calculate the watchdog
timeout in a way that's compatible with a Quark D2000 running at 32MHz;
a comment in adjust_timeout() explains this in more detail.
