tested on STM32MP135F-DK board, stm32mp13_defconfig.

I have a dependency with patch "firmware: scmi: fix the multi channel 
support with CCF"

http://patchwork.ozlabs.org/project/uboot/patch/20220930093635.1.I38e66d79350b381b6059a6a80ce60c62f01f3894@changeid/


This this patch the SD-Card boot is OK with 2 traces :


1- because USBPHY is not yet present in DT:

clk_register: failed to get ck_usbo_48m device (parent of usbo_k)


2- the console trace is pertubated by UART RESET introduction in DT

=> the UART FIFO is not flush before the probe after relocation

       and the reset of HW device

Clocks:
- MPU : 650 MHz
- AXI : 266.500 MHz
- PER : 24 MHz
- DDR�Core:  165 devices, 23 uclasses, devicetree: board
MMC:   STM32 SD/MMC: 0


For information "clk dump" command cause a crash because the SCMI clock

are not probed when clk_get_rate is used,  but I prepare a patch to 
avoid this issue.


Thanks
