[PATCH] ASoC: mediatek: mt2701: fix snprintf bounds

[Rosen Penev <rosenp@gmail.com>]

For whatever reason, GCC is unable to figure out that i2s_num is a
single digit number, with MT2701_BASE_CLK_NUM being the maximum value it
represents. Add a min() call to help it out and fix W=1 errors regarding
snprintf bounds.
