ALSA: hda - Enable mic-mute LED on more HP laptops

The newer HP laptops have SSID 103c:20xx and 103c:21xx, and these
usually have the mic-mute LED on Fn-F8.  Let's enable it, too.

ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at remove

As drvdata is cleared to NULL at probe failure or at removal by the
driver core, we don't have to call pci_set_drvdata(pci, NULL) any
longer in each driver.

The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
hda_intel.c.  Since this function itself releases the card instance,
we need to clear drvdata here as well, so that it won't be released
doubly in the remove callback.

sound: OSS: Remove superfluous pci_set_dvdata(pci, NULL)

Only kahlua.c has it.

ALSA: ISA: Remove superfluous *_set_drvdata(NULL) calls

Similarly like the previous commit for PCI drivers, remove
dev_set_drvdata(NULL) and pnp_set_drvdata(NULL) calls in ISA drivers
now.

ALSA: Remove the rest of *_set_drvdata(NULL) calls

A few calls are still left in parport drivers after this commit, which
I'm not quite sure yet.
