[PATCH] ALSA: usb-audio/line6: Add support for POD HD PRO

[Phil Willoughby <willerz@gmail.com>]

The POD HD PRO is the rackmount version of the POD 500, with most of the
same behaviors. As with some of the other rackmount POD devices it will
not send captured audio to the host unless the host is sending playback
audio, so it has LINE6_CAP_IN_NEEDS_OUT in addition to the POD 500
flags.
