Sorry, I don't see any reason for changing the DT definition of the pll6.
The clock is named "pll6" with "#clock-cells = <1>;" in all DTs,
and it works as it is.
If you want an other clock as "pll8", with the same HW description,
you must add new code for this clock.

The datasheet says that the pll6x2 output is 24 MHz * n * k, then, if
I remember correctly my lessons at primary school, defining pll6 as
(pll6x2 / 2) gives 24 MHz * n * k / 2 as the pll6 output. No?
