[PATCH v2 2/2] selftests: test possible usb type values from documentation

[Boris Shtrasman]

modify kselftest to check for usb_types values from
Documentation/ABI/testing/sysfs-class-power instead of only checking for
property.

Added the
"Unknown", "SDP", "DCP", "CDP", "ACA", "C", "PD",
"PD_DRP", "PD_PPS", "BrickID", "PD_SPR_AVS",
"PD_PPS_SPR_AVS" values from the
 /sys/class/power_supply/<supply_name>/usb_type section.
