pinctrl: pinctrl-imx: don't use invalid value of conf_reg

Browse source

commit 4ff0f034e9 upstream.

The right check for conf_reg to be invalid it testing against -1 not 0
as is done in the rest of the driver.

This fixes an oops that can be triggered by:

	cat /sys/kernel/debug/pinctrl/43fac000.iomuxc/*
