[PATCH] Blackfin: bf537: use "CONFIG_SND_SOC_AD193X"

[Paul Bolle <pebolle@tiscali.nl>]

Commit 57084ede395bb3c9da7905701d34a3b7d33c9356 ("blackfin: bf537:
stamp: update board file for 193x") changed two references to
CONFIG_SND_BF5XX_SOC_AD193X (and CONFIG_SND_BF5XX_SOC_AD193X_MODULE).
One was changed to CONFIG_SND_SOC_AD193X_SPI, the other to
CONFIG_SND_SOC_AD193X_I2C. The commit explanation doesn't elaborate on
the reason for these changes nor on the reason to drop module support.

Anyhow, neither of these two new Kconfig macros is valid. It was
probably intended to use CONFIG_SND_SOC_AD193X here. So let's use that.
And let's also reenable module support by using the IS_ENABLED() macro.

0) Untested. Please note that I fail to see the point of commit
57084ede395bb3c9da7905701d34a3b7d33c9356, which was added in v3.4, even
if I assume it wanted to use CONFIG_SND_SOC_AD193X. Perhaps I'm missing
something obvious. Anyhow, review is appreciated.

1) Added Jean and Guenter because they seem to take in interest in
Blackfin's stamp files.
