ARM: dts: stm32: support child mfd cells for the stm32mp1 TAMP syscon
The stm32mp1 TAMP peripheral has 32 backup registers that survive
a warm reset. This makes them suitable for storing a reboot
mode, which the vendor's kernel tree is already doing[0].
The actual syscon-reboot-mode child node can be added by a board.dts or
fixed up by the bootloader. For the child node to be probed, the
compatible needs to include simple-mfd. The binding now specifies this,
so have the SoC dtsi adhere to it.
