[PATCH] ARM: tegra: Add core supply for Tegra114 boards

[PATCH] ARM: tegra: Add core supply for Tegra114 boards

[Mikko Perttunen]

After commit 4cc90d4c043e ("ARM: tegra: Configure Tegra114 power
domains"), a core-supply property is required in the PMC node.
Label the core regulator on Dalmore, NVIDIA SHIELD and Tegra Note 7
and add the property.

Fixes: 4cc90d4c043e ("ARM: tegra: Configure Tegra114 power domains")

This skips TF701T since there is already a patch on the mailing list for 
it. Tested on Dalmore, but not on TN7 or SHIELD Portable.
