ALSA: hda/realtek: Workaround for resume on Dell Venue 11 Pro 7130

Browse source

[ Upstream commit 8c2fa44132 ]

It was reported that the headphone output on Dell Venue 11 Pro 7130
becomes mono after PM resume.  The cause seems to be the BIOS setting
up the codec COEF 0x0d bit 0x40 wrongly by some reason, and restoring
the original value 0x2800 fixes the problem.

This patch adds the quirk entry to perform the COEF restore.
