this mode instead of the integer one.
When calculating the PLL3 freq for the dotclock, check if it is a multiple
of the fracional frequencies.

The audio controller in the H3 is more or less the same as A10/A20 except
some registers are shuffled around. The mixer interface, however, is
completely different between SoCs. Separate a10_mixer_class and
h3_mixer_class implementations are now made available. This will also make
adding support for other SoCs easier in the future.

When sensor 0's alarm interrupt is fired, set a throttle flag. Further
requests to set CPU frequency will be rejected until sensor 0's temperature
returns to a level below the hot temperature threshold.

When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().
Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.
While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

Do a hard reset of the controller before a soft one.
Since DMA is always used remove dependancy on allwinner_soc_family, it was used
to differentiate SoC as the fdt compatible string were the same.
