Idea is to expose dai links or codec confs via members of machine driver
structure. The 'struct tegra_asoc' is used to group dai link related
members, which would be included in the 'struct tegra_machine'. This helps
to simplify the code like mentioned below.
* no need of having t21x or t18x specific helper functions
* no need of having global variables. Currently we use few global members
for t21x.
* currently we have separate helpers to first pass DT dai-links and then
append with the dai-links defined in machine-alt utility code. In the
current patch new helper{tegra_asoc_populate_dai_links()} combines both
of the operations. The same is true for codec conf helpers as well and
tegra_asoc_populate_codec_confs() alone is sufficient.
* machine driver codec_init() and set_dai_ops() for easy reading.
In summary,
tegra_asoc_populate_dai_links() combines following.
* tegra_machine_new_codec_links()
* tegra_machine_append_dai_link()
* tegra_machine_append_dai_link_t18x()
tegra_asoc_populate_codec_confs() combines following.
* tegra_machine_new_codec_conf()
* tegra_machine_append_codec_conf()
* tegra_machine_append_codec_conf_t18x()
machine->asoc->dai_links/codec_confs replaces below helpers.
* tegra_machine_get_dai_link()
* tegra_machine_get_dai_link_t18x()
* tegra_machine_get_codec_dai_link_idx_t18x()
* tegra_machine_get_codec_conf()
* tegra_machine_get_codec_conf_t18x()
Machine driver(tegra_machine_driver_mobile.c) exposes add_dai_links()
helper to setup dai links. This will be used in the subsequent patches in
the series. Few structures are moved to machine-alt header files for reuse
if needed by other machine drivers. Also release_asoc_phandles() is exposed
to balance refcounts, during error paths, by calling of_node_put() for DAI
links and codec conf.
