The DPLL USB can generate higher speed (x2) than the regular ones.
The max multiplication value is then twice the previous value.
Fix both max_mult and max_div with that correct values.
Change the max_div variable type to u16 to allow storing up to 256.
Replace as well the define with the value to avoid
unneeded indirection and provide a better readability.
Remove the defines that become useless.
