ASoC: omap: Remove needless prints from machine drivers

It is currently completely normal to execute these machine drivers code on
different boards if the kernel includes support for multiple boards so no
error message should be printed if the machine_is_xxx does not match with
the machine driver.

Therefore remove these pr_err and pr_debug prints in those cases.
