mtd: spinand: winbond: Prevent unsupported frequencies on dual/quad I/O variants
Dual and quad capable chips natively support dual and quad I/O variants at up to 104MHz (1-2-2 and 1-4-4 operations). Reaching the maximum speed of 166MHz is theoretically possible (while still unsupported in the field) by adding a few more dummy cycles. Let's be accurate and clearly state this limit. Setting a maximum frequency implies adding the frequency parameter to the macro, which is done using a variadic argument to avoid impacting all the other drivers which already make use of this macro.
