Introduce the "dpm_watchdog_enabled" module parameter to allow the DPM watchdog to be enabled or disabled at boot time and runtime. Additionally, introduce the CONFIG_DPM_WATCHDOG_ENABLED Kconfig option to set the default value of the module parameter at compile time. The primary motivation for this configurability resolves around Android GKI (Generic Kernel Image). We want to enable CONFIG_DPM_WATCHDOG in the GKI so the feature is available. However, because the GKI is shared across many different devices, we don't want to inadvertently affect devices that are unaware of this feature. This provides a way to compile it in, but keep it disabled by default for those devices via the kernel command line or module parameters. To maintain backward compatibility, CONFIG_DPM_WATCHDOG_ENABLED relies on `default y`. Previously, the DPM watchdog was always active if CONFIG_DPM_WATCHDOG was set. Defaulting this new option to 'y' ensures that the behavior remains unchanged for existing users and defconfigs when they upgrade.
