[Laxman Dewangan <ldewangan@nvidia.com>]

Device ams AS3722 supports the one 32KHz clock output. The clock control
support is provided through clock driver.

Add clock driver as mfd sub device to probe the clock driver.

+======
+AS3722 supports one 32KHz clock to output from device. The clock control is
+provided through the clock driver.
+This binding uses the common clock binding ./clock-bindings.txt.
+The device node should have the optional properties to support the clock:
+#clock-cells: from common clock binding; shall be set to 1. The clock id for
+	single clock output is 0.
