- Get rid of incomprehensible "if { for { if } }" construction for the
exponential divisor calculation. The first if statement isn't correct
at all, since it should check for "host->max_clk / pre_div / 16 >
clock". The error doesn't cause any bugs because the check in the for
loop does the right thing, and so the outer check becomes useless;
- For the linear divisor do the same: a single while statement is more
readable than for + if construction;
- Add dev_dbg() that prints desired and actual clock frequency.
