Add the new rk817 codec driver to the Odroid Go Advance.

Tested-by: Maciej Matuszczyk <[e-mail]>

Changes in v9:
 - Add cover letter.
 - Remove documentation for interrupt parent per Rob Herring's request.
 - Remove unused MODULE_DEVICE_TABLE to fix a bug identified by kernel test
   robot.
Changes in v8:
 - Added additional documentation for missing properties of #sound-dai-cells,
   interrupt-parent, and wakeup-source for mfd documentation.
 - Corrected order of elements descriptions in device tree documentation.
 - Changed name of "mic-in-differential" to "rockchip,mic-in-differential".
 - Changed name of sound card from "rockchip,rk817-codec" to "Analog".
 - Removed unused resets and reset-names from the i2s1_2ch node.
Changes in v7:
 - Removed ifdef around register definitions for MFD.
 - Replaced codec documentation with updates to MFD documentation.
 - Reordered elements in example to comply with upstream rules.
 - Added binding update back for Odroid Go Advance as requested.
 - Submitting patches from gmail now.
Changes in v6:
 - Included additional project maintainers for correct subsystems.
 - Removed unneeded compatible from DT documentation.
 - Removed binding update for Odroid Go Advance (will do in seperate series).
Changes in v5:
 - Move register definitions from rk817_codec.h to main rk808.h register
   definitions.
 - Add volatile register for codec bits.
 - Add default values for codec bits.
 - Removed of_compatible from mtd driver (not necessary).
 - Switched to using parent regmap instead of private regmap for codec.
Changes in v4:
 - Created set_pll() call.
 - Created user visible gain control in mic.
 - Check for return value of clk_prepare_enable().
 - Removed duplicate clk_prepare_enable().
 - Split DT documentation to separate commit.
Changes in v3:
 - Use DAPM macros to set audio path.
 - Updated devicetree binding (as every rk817 has this codec chip).
 - Changed documentation to yaml format.
 - Split MFD changes to separate commit.
Changes in v2:
 - Fixed audio path registers to solve some bugs.
