mtd: nand: denali: remove detect_partition_feature()
The denali->fwblks is set by detect_partition_feature(), but it is
not referenced from anywhere. That means the struct member fwblks
and the whole of detect_partition_feature() are unneeded.
The comment block implies this function is only for Intel platforms.
I found drivers/staging/spectra used to exist, but it was deleted by
commit be7f39c5ecf5 ("Staging: delete spectra driver") 5 years ago.
So, I guess nobody would need this function any more.
