The snd_hdac_chip_readl return can never be less than zeros,
so no point in checking for the return value
This fixes following static checker warnings in
snd_hdac_ext_bus_parse_capabilities
sound/hda/ext/hdac_ext_controller.c:47
snd_hdac_ext_bus_parse_capabilities()
warn: unsigned 'offset' is never less than zero.
sound/hda/ext/hdac_ext_controller.c:54
snd_hdac_ext_bus_parse_capabilities()
warn: unsigned 'cur_cap' is never less than zero.

In HDA extended bus the HDA link objects are created when multilink
capabilities are parsed. We need a routine which free up these link objects
for a bus. So add snd_hdac_link_free_all routine

The controller needs to support the new capabilities and allow
reading, parsing and initializing of these capabilities, so this patch
does it
