s32: drivers: s32ze: adc: patch to fix the issue clear the EOC flag

Clear the EOC flag before Adc_Sar_CheckAndCallEocNotification() is
called to avoid the race condition that prevents the next end of
conversion callback to be executed, when a conversion is started
inside the previous end of conversion completed callback.
