This series adds Allwinner A64 audiocodec support into sun4i-i2s,
sun8i-codec drivers, introduces new sun50i-codec-analog driver and enables
sound on Pine64, SoPine boards and Pinebook.

I2S for audiocodec in A64 is different from other 3 I2S modules but
similar to one in A10, digital part of codec is compatible with A33 and
analog controls part is completely different from other SoCs - it shares
only few bits in few registers, so adding support for it into existing
sun8i-codec-analog would mean duplicating all the widgets, controls and
some routes and making it hard to read. Therefore it makes sense to
introduce new driver.

v2: - Use simple-amplifier for speaker amp on Pinebook
    - Rename sun50i-a64-i2s to sun50i-a64-codec-i2s to preserve compatible
      string for other 3 I2S modules in A64 in case if there's any
      incompatibility with H3
v3: - renamed sunxi-adda-pr-regmap to sun8i-adda-pr-regmap
    - use ilog2() to calculate reg value for LRCK div instead of using a
      table
v4: - dts: don't use 'Mic' and 'Headset Mic' widgets from sun8i-codec,
      define our board-level widgets instead.
