> There are a few issues with the setup of the Actions Semi Owl S500 SoC's

> 
> * AHBPREDIV clock is defined as a muxer only, although it also acts as

> * H clock is using a wrong divider register offset
> * AHB is defined as a multi-rate factor clock, but it is actually just

> * Change AHBPREDIV clock to an ungated OWL_COMP_DIV definition.
> * Use the correct register shift value in the OWL_DIVIDER definition
>   for H clock
> * Drop the unneeded 'ahb_factor_table[]' and change AHB clock to an
>   ungated OWL_COMP_FIXED_FACTOR definition.
