ASoC: remove unused ep93xx files
A couple of ep93xx board files were unused and got removed, so the corresponding ASoC support can also be removed. Cc: Mika Westerberg <mika.westerberg@iki.fi> Cc: Ryan Mallon <rmallon@gmail.com> Acked-by: Mark Brown <broonie@kernel.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
