Required properties:
- compatible : Should be "nvidia,<chip>-sdhci"
- reg : Should contain eSDHC registers location and length
- interrupts : Should contain eSDHC interrupt
- reg : Should contain SD/MMC registers location and length
- interrupts : Should contain SD/MMC interrupt

Optional properties:
- cd-gpios : Specify GPIOs for card detection
- wp-gpios : Specify GPIOs for write protection
- power-gpios : Specify GPIOs for power control
- support-8bit : Boolean, indicates if 8-bit mode should be used.
