usb: pd: Support Programmable Power Supply as sink

PD 3.0 version 1.1 includes a new Programmable Power Supply
type that can be sent as an Augmented Power Data Object in a
Source Capabilities message. Add sink-side support to request an
Augmented PDO which also includes specifying the source's output
output voltage and current. For userspace, overload the 'select_pdo'
sysfs attribute by allowing voltage (uV) and current (uA) to be
optionally written, with the following syntax:

	echo <src cap id> <PDO> [<uV> <uA>] > select_pdo

Also rename the 'rdo' file to 'rdo_h' as it is already in human-
readable format, enhance it with APDO values, and make 'rdo' simply
spit out the hex value.
