arch: dts: am642-sk-u-boot: Disable main_sdhci0 DT node and define alias index 1...

A Wilink wireless device is connected to MMCSD0 subsystem and is not
supported in U-Boot. Therefore, disable main_sdhci0 device tree node in
U-Boot.

If main_sdhci0 device tree node is disabled then the the index of
main_sdhci1 node becomes 0 which leads to break in boot flow. Therefore,
add an alias to fix the index to 1.
