arm64: tegra: Enable SDHCI controllers on P3110
The P3110 processor module wires one of the SDHCI controllers to an on-
board eMMC and exposes another set of SD/MMC signals on the connector to
support an external SD/MMC card. A third controller is connected to the
SDIO pins of an M.2 KEY E connector.
