Subject: [PATCH v5 2/9] watchdog: rzg2l_wdt: Make the driver depend on PM

From: Claudiu Beznea <[email protected]>

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. Along
with it the dependency on CONFIG_PM and CONFIG_COMPILE_TEST was moved to a
new line to have the code simpler.

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

Please drop this change (i.e. retain the "|| COMPILE_TEST"), as it prevents
compile-testing on any platforms but RZ/G2L(alike) and RZ/V2M.
