If we have Linux installed in eMMC we can boot without µSD card, but inserting one is not recognised.
The reason is that the card detect gpio (gpio5_152) is not configured and attached to the mmc1 interface driver and the mmc driver does not poll by default.
Hence we add pinmux and gpio setup for the SDCARD_NCD signal.
