[PATCH 3/4] ARM: dts: stm32mp: reuse now upstream tamp node

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Since 6ea3de1b8ce7 ("dts: update to v5.11-rc1"), the upstream device
tree now has a node with simple-mfd, which we can add our reboot mode
beneath without having to replicate information, so make use of that.

No functional change.
