Subject: [PATCH] pinctrl: amd: Don't show `Invalid config param` errors

On some systems amd_pinconf_set() is called with parameters
0x8 (PIN_CONFIG_DRIVE_PUSH_PULL) or 0x14 (PIN_CONFIG_PERSIST_STATE)
which are not supported by pinctrl-amd.

Don't show an err message when called with an invalid parameter,
downgrade this to debug instead.

Cc: stable@...r.kernel.org # 6.1
Fixes: 635a750d958e1 ("pinctrl: amd: Use amd_pinconf_set() for all config options")
