ALSA: usb-audio: Add quirk flag for ASUS SupremeFX Hi-Fi

The ASUS SupremeFX Hi-Fi (0b05:1826, 0b05:1827) does not survive USB
autosuspend.  After a suspend/resume cycle the firmware degrades: HID
probes begin to fail and the descriptors it returns become corrupted,
until the device stops responding entirely and needs a physical power
cycle to recover.

Add QUIRK_FLAG_DISABLE_AUTOSUSPEND for both product IDs.

Verified on 7.2.6 through the quirk_flags module parameter, with no
code change, and with the local udev rules that had been forcing
power/control commented out, so the parameter was the only mechanism
in play.  Both IDs were passed as

  0b05:1827:disable_autosuspend;0b05:1826:disable_autosuspend

The device then stayed awake across 2.5 hours (runtime_suspended_time
remained 0), survived a system suspend/resume cycle, and continued to
work afterwards with no failed probes and no power cycle needed.
