SND_SUN50I_CODEC_ANALOG selects SND_SUNXI_ADDA_PR_REGMAP which is leftover
of renaming SND_SUNXI_ADDA_PR_REGMAP to SND_SUN8I_ADDA_PR_REGMAP. Replace
it with SND_SUN8I_ADDA_PR_REGMAP to fix possible link errors for some
configurations:

sound/soc/sunxi/sun50i-codec-analog.o: In function `sun50i_codec_analog_probe':
sun50i-codec-analog.c:(.text+0x62): undefined reference to `sun8i_adda_pr_regmap_init'

Fixes: 42371f32 ("ASoC: sunxi: Add new driver for Allwinner A64 codec's analog path controls")
