Introduce a defconfig for the Qualcomm IPQ9574 SoC based RDPs.
Presently supports eMMC.
Per the flash memory layout, U-Boot size cannot exceed 756KB. With this
defconfig, u-boot.mbn size is ~480KB.

U-Boot has to reconfigure the clocks that were set in the boot
loaders. However, in IPQ9574, the clocks have to be reset before
they can be reconfigured. Hence add code to do the relevant
resets.
