6.13-stable review patch. If anyone has any objections, please let me know.

From: Marek Vasut marex@denx.de
[ Upstream commit a4422a9183278162093d4524fdf4b6bbd7dd8a28 ]
The STM32MP13xx DHCOR DHSBC is populated with STM32MP13xx part capable of 1 GHz operation, increase the CPU core voltage to 1.35 V to make sure the SoC is stable even if the blobs unconditionally force the CPU to 1 GHz operation.
It is not possible to make use of CPUfreq on the STM32MP13xx because the SCMI protocol 0x13 is not implemented by upstream OpTee-OS which is the SCMI provider.
