Fix audio for Allwinner H3/H5

[freebsdnewbie_freenet.de]

Summary

Due to three conditions the codec driver for Allwinner A10/A20 and H3/H5 did not work properly here:

1. Wrong bit position for the analog audio reset
2. Hardware Reset of codec was not de-asserted correctly
3. Linux DTS file did not contain the address of the analog register the way as the driver was expecting it.

This patch proposes fixes for those three parts.

Test Plan

The patch was successfully tested on a Allwinner NanoPI NEO2 hardware.

[freebsdnewbie_freenet.de]

Move H3/H5 specific setup into its mixer_init function.

Using reg[0] + reg[1] should work for the end parameter.

What's the reason for this stop here ?

[freebsdnewbie_freenet.de]

Changed "end"-parameter for resource allocation.

[freebsdnewbie_freenet.de]

Move codec_stop call to a different place.

Sometimes during testing the sound did not start the first time after a cold start/reboot. When i started the player once again, the sound was played correctly. I just wanted to set the peripheral to a known state before starting over. With this stop placed here, i could not reproduce the error during playing a sound the first time after reboot.
