[PATCH v4] DTS: ARM: OMAP5: uevm: add ÂSD card detect

[H. Nikolaus Schaller]

If we have Linux installed in eMMC we can boot without
ÂSD 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.
