I have tested this on an AYN Odin 3, which has a CQ8725S SoC with
A830. As-is, this change causes the device to fail to boot. Comparing
to a different implementation of this support that I used previously,
I found the operable difference is the count_max field here. Dropping
that from 64 to 15 allows the device to boot and work as intended. I
unfortunately don't have uart to see what the actual failure text is
and provide any more information than this.
