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 eefeb2b050 drivers: watchdog: esp32: Use common Kconfig option to disable at boot
Instead of relying on CONFIG_WDT_ESP32_DISABLE_AT_BOOT, use
CONFIG_WDT_DISABLE_AT_BOOT that's available for all watchdog timers.

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.
