The SPI chip selects are represented as:
cs-gpios = <&gpio4 11 GPIO_ACTIVE_LOW>, <&gpio4 13 GPIO_ACTIVE_LOW>;
, which means that they are used in GPIO function instead of native
SPI mode.
Fix the IOMUX for the chip select 1 to use GPIO4_13 instead of
the native CSPI_SSI function.
Fixes: c605cbf5e135 ("ARM: dts: imx: add device tree support for Freescale imx50evk board")
