watchdog: rzg2l_wdt: Rely on the reset driver for doing proper reset

[ Upstream commit d8997ed7 ]

The reset driver has been adapted in commit da235d2f
("clk: renesas: rzg2l: Check reset monitor registers") to check the reset
monitor bits before declaring reset asserts/de-asserts as
successful/failure operations. With that, there is no need to keep the
reset workaround for RZ/V2M in place in the watchdog driver.
