* Marvell SD8787 power sequence provider

Required properties:
- compatible: must be "mmc-pwrseq-sd8787".
- powerdown-gpios: contains a power down GPIO specifier with the
		   default active state
- reset-gpios: contains a reset GPIO specifier with the default
		   active state

Example:

	wifi_pwrseq: wifi_pwrseq {
		compatible = "mmc-pwrseq-sd8787";
		powerdown-gpios = <&twl_gpio 0 GPIO_ACTIVE_LOW>;
		reset-gpios = <&twl_gpio 1 GPIO_ACTIVE_LOW>;
