[PATCH v2 1/4] pinctrl: mcp23s08: Do not complain about unsupported params

[Jan Kundrát <jan.kundrat@xxxxxxxxx>]

It is expected that some of these operations won't work on each and
every HW. Previously, even a simple `cat
/sys/kernel/debug/pinctrl/spi1.1/pinconf-pins` caused excessive dmesg
output.

v2: In the set path, just downgrade to dev_dbg instead of removing the
log altogether based on Phil's and Linus' feedback.
