There's quite a few watchdog drivers which are easily enabled for
COMPILE_TEST, so let's enable them.

This patch adds the of_match_table to enable DT support
of Loongson-1 watchdog driver.
And modify the parameter of devm_clk_get_enabled() accordingly.

Implement restart handler for the Loongson-1 watchdog driver and
define the watchdog registers instead of including the legacy header.

The devm_clk_get_enabled() helper:
- calls devm_clk_get()
- calls clk_prepare_enable() and registers what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
This simplifies the code and avoids the need of a dedicated function used
with devm_add_action_or_reset().

improvements
Use device managed functions to simplify error handling, reduce
source code size, improve readability, and reduce the likelyhood of bugs.
Other improvements as listed below.
The conversion was done automatically with coccinelle using the
following semantic patches. The semantic patches and the scripts
used to generate this commit log are available at
https://github.com/groeck/coccinelle-patches
- Drop assignments to otherwise unused variables
- Drop unnecessary braces around conditional return statements
- Drop empty remove function
- Use devm_add_action_or_reset() for calls to clk_disable_unprepare
- Introduce local variable 'struct device *dev' and use it instead of
dereferencing it repeatedly
- Use devm_watchdog_register_driver() to register watchdog device
