properies like wakeup and no_control_vbus can be represented in boolean,
so read those properties using of_property_read_bool.
Also updated the documentation with device tree binding information for
palmas-usb.

+PALMAS USB COMPARATOR
+Required Properties:
+ - compatible : Should be "ti,palmas-usb"
+ - interrupts : Four interrupt numbers to the cpu should be specified. First
+ interrupt number is the otg interrupt number that raises ID interrupts when
+ the controller has to act as host and the second interrupt number is the
+ ID wakeup interrupt number, third interrupt is VBUS interrupt and fourth
+ interrupt is VBUS wakeup interrupt.
+- interrupt-name : the name corresponding to each interrupt populated in
+ interrupts property.
+ - vbus-supply : phandle to the regulator device tree node.
+
+Optional Properties:
+ - ti,wakeup : To enable the wakeup comparator in probe
+ - ti,no_control_vbus: if the platform wishes its own vbus control
