can: peak_usb: add forgotten supported devices

[ Upstream commit 59ec7b89ed3e921cd0625a8c83f31a30d485fdf8 ]

Since the peak_usb driver also supports the CAN-USB interfaces
"PCAN-USB X6" and "PCAN-Chip USB" from PEAK-System GmbH, this patch adds
their names to the list of explicitly supported devices.

Fixes: ea8b65b5 ("can: usb: Add support of PCAN-Chip USB stamp module")
Fixes: f00b534d ("can: peak: Add support for PCAN-USB X6 USB interface")
