Update the rzv2h_wdt driver to make the "oscclk" clock and reset
controller optional.

Use devm_clk_get_optional_prepared() to obtain the "oscclk" clock,
allowing the driver to work on platforms that do not provide this clock,
such as the RZ/T2H SoC.

Similarly, use devm_reset_control_get_optional_exclusive() to allow the
driver to function on platforms that lack a reset controller.

These changes are preparatory steps for supporting the RZ/T2H SoC, which
does not provide an "oscclk" clock or a reset controller.
