6Required properties:
7- compatible : Should be "fsl,<chip>-esdhc"
8- reg : Should contain eSDHC registers location and length
9- interrupts : Should contain eSDHC interrupt
10
11Optional properties:
12- fsl,card-wired : Indicate the card is wired to host permanently
13- fsl,cd-controller : Indicate to use controller internal card detection
14- fsl,wp-controller : Indicate to use controller internal write protection
15- cd-gpios : Specify GPIOs for card detection
16- wp-gpios : Specify GPIOs for write protection
