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

From: Mario Limonciello <mario.limonciello@xxxxxxx>

commit 87b549efcb0f7934b0916d2a00607a878b6f1e0f upstream.

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.
