The audio divider is one based. This offset was mistakenly dropped from
recalc_rate() when migrating to clk_regmap.

The audio divider needs a specific clock divider driver.
With am mpll parent clock, which is able to provide a fairly precise rate,
the generic divider tends to select low value of the divider. In such case
the quality of the clock is very poor. For the same final rate, maximizing
the audio clock divider value and selecting the corresponding mpll rate
gives better results. This is what this driver aims to acheive. So far, so
good.
