Add Tsin A pins to bank DV and X.
We don't have a driver for the tsin yet but since the tsin A pinmux is
enabled by default at boot time, declaring this pinmux is required to
properly operate on GPIOX.
Without this change, GPIOX 8, 9, 10 and 11 can't be driven as GPIO output
as the tsin A seems to have priority.

Should this get a Fixes header then for stable backports?

Looks OK AFAICT.

Nothing is wrong with what is already in. This is merely an addition.
If we go that way, all commit to this file should have a Fixes to the
initial commit. This seems a bit extreme to me ...

Your above description of not being able to use GPIOs on e.g. the GXL
based Khadas Vim devboard sounded like a bug to me.

Thought it might have been just an oversight.

As far as I know, the affected pins (GPIOX 8 to 11) are used for BTPCM, not
GPIOs, on all supported designs, including the Vim.
