[media] drx-j: be sure to send the powerup command at device open
As drxj_close puts the device in powerdown, we need to power it up properly at drxj_open. This is the behavior noticed at the Windows driver. Acked-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
