ARM: dts: imx7d-flex-concentrator: fix pcf2127 reset

RTC pcf2127 device driver has changed default behaviour of the watchdog
feature in v5.11-rc1. Now you need to explicitly enable it with a
device tree property, "reset-source", when used in the board design.

Fixes: 71ac13457d9d ("rtc: pcf2127: only use watchdog when explicitly available")
