On Marvell mv88f6180 with pin control driver one can not use multi
purpose pins 35 through 44.
I'm using this controller on an embedded board and i found that the
pin multiplexing is not the same as in the hardware spezification.
This patch alters the pin description so that mpp pins 0 to 19 as well
as 35 to 44 are usable.
Pin settings i used can be found here:

Hi Andreas,
sorry for the delay. I double-checked the HW datasheet above and can
confirm that 6180 uses MPP[19:0] and MPP[44:35], i.e. there is a hole
in the middle.
So, looking at your patch, you basically move MPP[n] to MPP[n+15]
starting with MPP[20] to match the HW spec.
That's fine with me, if it works on 6180 Kirkwood.

And we should probably have a Fixes: tag + stable.

Ok. Thanks for the confirmation.
However, I thought about it an realized that
we probably copied the 6180 table from the
old platform driver pre-dating pinctrl-API.
That is why for 6180 there is no hole as gpios
had to be continuous back then.
I cannot check right now, but if we already have
a mainlined board dtb with 6180 we have to
update that as well. If not, the change is
painless.

I now think we don't need a fixed tag and it
should not go to stable. It is probably the
first time anyone uses DT pinctrl-API for 6180.
