can: gs_usb: activate quirks for CANtact Pro unconditionally

The CANtact Pro from LinkLayer Labs is based on the LPC54616 µC, which
is affected by the NXP LPC USB transfer erratum. However, the current
firmware (version 2) doesn't set the
GS_CAN_FEATURE_REQ_USB_QUIRK_LPC546XX bit.

This patch sets the feature GS_CAN_FEATURE_REQ_USB_QUIRK_LPC546XX to
workaround this issue.

For the GS_USB_BREQ_DATA_BITTIMING USB control message the CANtact Pro
firmware uses a request value, which is already used by the
candleLight firmware for a different purpose
(GS_USB_BREQ_GET_USER_ID).

This patch set the feature GS_CAN_FEATURE_QUIRK_BREQ_CANTACT_PRO to
workaround this issue.
