arm64: tegra: Fix mmc0 alias for Jetson Xavier NX 



There are two variants of the Jetson Xavier NX platform; one has an
eMMC and one as a micro SD-card slot. The SDHCI controller used by
each variant is different, however, the current device-tree for both
Xavier NX boards have the same SDHCI controller defined as 'mmc0' in
the device-tree alias node. Fix this by correcting the 'mmc0' alias
for the SD-card variant.
