Adding gpio-line-names property works fine for this

Allow to add property gpio-line-names for this devices.

No worries, this can be ignored. Warning messages can pass the limit (up
to some point).
Fine, thanks!
Ignored, as it is a make output, which helps to understand the
reason for adding this patch.

I think gpio-line-names should always match the actual number of GPIOs
for given device. Do you have here devices with 1 gpio? This could be
further constrained in if:then sections.
I have the device with "sx150x_16_pins", see drivers/pinctrl/pinctrl-sx150x.c
I started with minItems, because I thought it is okay to allow
less names... (as I did in patch 3/3) but see now, that other drivers have
minItems = maxItems.
So I think I should add to my patch the following part:

With that, dtb checks than claim (as expected) for my 3/3 patch
from this seris:
"""
imx8mp-aristainetos3-proton2s.dtb: pinctrl@3f: gpio-line-names: ['RELAY0', 'RELAY1', 'RELAY2',
'HEATER', 'FAN', 'SPARE', 'CLEAR', 'FAULT'] is too short
"""
So, I adapt that too in a next version of the patchset, if above
change is okay... is it?
Thanks for your review!
bye,
Heiko
