      ASoC: sunxi: sun4i-codec: fill ASoC card owner · 7c0d6e48

      card->owner is a required property and since commit 81033c6b ("ALSA:
      core: Warn on empty module") a warning is issued if it is empty. Add it.
      This fixes following warning observed on Lamobo R1:

      Merge series "Do not handle MCLK device clock in simple-card-utils" from Sameer Pujar <spujar@nvidia.com>:
      
      With commit 1e30f642 ("ASoC: simple-card-utils: Fix device module clock")
      simple-card-utils can control MCLK clock for rate updates or enable/disable.
      But this is breaking some platforms where it is expected that codec drivers
      would actually handle the MCLK clock. One such example is following platform.
        - "arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var3-ads2.dts"
      
      In above case codec, wm8904, is using internal PLL and configures sysclk
      based on fixed MCLK input. In such cases it is expected that, required PLL
      output or sysclk, is just passed via set_sysclk() callback and card driver
      need not actually update MCLK rate. Instead, codec can take ownership of
      this clock and do the necessary configuration.
      
      So the original commit is reverted and codec driver for rt5659 is updated
      to fix my board which has this codec.
