pinctrl: freescale: imx: fix bogus check of of_iomap() return value
commit 9a4f424531dabd877259ae0071b8bcc4dede9eb5 upstream.
On error path of_iomap() returns NULL, hence IS_ERR() check is invalid
and may cause a NULL pointer dereference, the change fixes this
problem.
While we are here invert a device node check to simplify the code.
