Subject: [PATCH v9 2/9] watchdog: rzg2l_wdt: Make the driver depend on PM

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

The rzg2l_wdt watchdog driver cannot work w/o CONFIG_PM=y (e.g. the
clocks are enabled though pm_runtime_* specific APIs). To avoid building
a driver that doesn't work make explicit the dependency on CONFIG_PM.

Changes in v9:
- collected Guenter's Rb tag

Changes in v8:
- collected tags

Changes in v7:
- updated the dependency to PM || COMPILE_TEST to be able to

  !(ARCH_RZG2L || ARCH_R9A09G011) platform and CONFIG_PM is disabled

Changes in v6:
- update patch description
- fixed the dependency on COMPILE_TEST previously introduced

Changes in v5:

Changes in v3:
- make driver depend on PM; with that the "unmet direct dependency"
