* This disables support for the RockPI-S "SDNAND" soldered on EMMC storage
Without it, SDNAND functions
There are no issues on boards that lack the EMMC storage option
In this case, the kernel probes the chip, quietly fails and continues without
creating the corresponding /dev/mmcblk* nodes
* This patch attempts to enable CPU operating points that are not defined.
The result is that the cpufreq-dt driver aborts when attempting to process these incompletely defined nodes.
The CPU ends up running at a constant clock rate, without cpufreq support.
Simply removing the patch restores proper cpufreq operation.
Note, however, that the CPU operating points are still overvolted for the newer RK3308B-S SOC.
