[PATCH] SOUND/SPI: Fix "clk_round_rate" undefined reference error.

[Majunath Goudar]

This patch adds a COMMON_CLK dependency to configure the
SND_AT73C213 for Atmel AT73C213 DAC driver. Without this patch,
build system can lead to build failure. This was observed during
randconfig testing, in which SND_AT73C213 was enabled w/o COMMON_CLK
being enabled. leading to the following error:

sound/built-in.o: In function `snd_at73c213_probe':
:(.text+0x328c4): undefined reference to `clk_round_rate'
make: *** [vmlinux] Error 1
