[PATCH 3/8] gpio: tqmx86: change tqmx86_gpio_write() order of arguments to match regmap API

[Matthias Schiffer]

Conversion to actually use regmap does not seem useful for this driver,
as regmap can't properly represent separate read-only and write-only
registers at the same address, but we can at least match the API to make
the code clearer.

No functional change intended.
