ALSA: hda_intel: add card number to irq description
Currently the info in /proc/interrupts doesn't allow to figure out which
interrupt belongs to which card (HDMI, PCH, ..).
Therefore add card details to the interrupt description.
With the patch the info in /proc/interrupts looks like this:
PCI-MSI 442368-edge snd_hda_intel:card1
PCI-MSI 49152-edge snd_hda_intel:card0
NOTE: this patch adds the new irq_descr field snd_card struct that is
filled automatically at a card object creation. This can be used
generically for other drivers as well. The changes for others will
follow later -- tiwai
