sdhci-of: cleanup eSDHC's set_clock() a little bit
- 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.
