watchdog: rzg2l_wdt: Fix reset control imbalance
Both rzg2l_wdt_probe() and rzg2l_wdt_start() calls reset_control_
deassert() which results in a reset control imbalance.
This patch fixes reset control imbalance by removing reset_control_
deassert() from rzg2l_wdt_start() and replaces reset_control_assert with
reset_control_reset in rzg2l_wdt_stop() as watchdog module can be stopped
only by a module reset. This change will allow us to restart WDT after
stop() by configuring WDT timeout and enable registers.
