Based on a datasheet [0] I found online, this flash seems to have SFDP.
And since you do not add any flash specific fixups, it likely does not
need an entry and would work fine with the generic flash driver. Did you
try using that? See [1] for more info on contribution guidelines.

I ran mtd_debug read/write tests on this flash, without adding flash
entry, it worked fine for me. Please ignore this patch.
