[PATCH v2 1/2] arm64: tegra: Enable SDHCI controllers on P3110

From: Thierry Reding <treding at nvidia.com>
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.

Changes in v2:
- move SD_CARD_SW_PWR regulator to carrier board (separate patch)
- move status = "okay" to carrier board
- fix card-detect GPIO for SDMMC1
