Uses timeout value of watchdog device directly, without modifying it
with ioctl. On some platforms, especially these with multiple watchdog
devices, the timeout values can be strictly defined for the watchdogs to
timeout in a certain order. Leaves timeout value as it is and divides
minimal of them by 2 as watchdog kicking period.

Handles systems with multiple watchdog hardware blocks. Identifies
each watchdog via the glob pattern
`/sys/devices/platform/*.watchdog_cl*/watchdog/watchdog*` to sysfs
path, and initializes and services each of them.

Watchdogd should be alive to complete shutdown

watchdogd.
