Introduce local variable 'struct device *dev' and use it instead of
dereferencing it repeatedly. Also replace 'ret = func(); return ret;'
with 'return func();'.

The patch "watchdog: da9062: use protection delay mechanism from core"
(fb484262) removed the only user of j_time_stamp. This turned into some
leftover functions that are removed with this patch.

The DA9062 watchdog occasionally enters error condition and resets the
system if the timeout is changed quickly after the timer was enabled.
The method of disabling and waiting for > 150 µs before setting the
new timeout is taken from the DA9052 driver.

Register a restart handler for the da9062 watchdog. System restart is
triggered by sending the shutdown command to the PMIC.
As more-suitable restart handlers may exist, the priority of the
watchdog restart handler is set to 128.

Use device managed functions to simplify error handling, reduce
source code size, improve readability, and reduce the likelyhood of bugs.

The of_device_id match array is added to support "dlg,da9062-watchdog"
as a valid .compatible string. A MODULE_DEVICE_TABLE() macro is added.
This patch assumes the use of a DA9062 fallback compatible string for the
DTS to pick up the DA9062 device driver for use with the DA9061 watchdog
hardware
Copyright header is updated to add DA9061 in its description and the module
description macro is extended to include DA9061.
Kconfig is updated to reflect support for DA9061/62.

/sys/class/watchdog/watchdogn/device/modalias can help to identify the
driver/module for a given watchdog node. However, many wdt devices do not
set their parent and so, we do not see an entry for device in sysfs for
such devices.
This patch fixes parent of watchdog_device so that
/sys/class/watchdog/watchdogn/device is populated.
Exceptions: booke, diag288, octeon, softdog and w83627hf -- They do not
have any parent. Not sure, how we can identify driver for these devices.
