Subject: [PATCH 1/6] ARM: dts: stm32: lxa-tac: disable the real time clock

From: Leonard Göhrs <l.goehrs@...gutronix.de>

The RTC was enabled under the false assumption that the SoM already
contains a suitable 32.768 kHz crystal.

It does however not contain such a crystal and since none is fitted
externally to the SoM the RTC can not be used on the hardware.

Reflect that in the devicetree.
