R40 analog codec

[Roman Elshin]

Hi, I am trying  to get works analog audio output  on Banana Pi M2
Ultra  sbc (it is based on sun8i-r40 soc). This patch (against 5.3.1)
make it works,  but there are some confusing things in dmesg:

~# dmesg |grep codec

The patch itself are correct ?, it would be a great  to have analog
audio working with mainline kernel.
