ASoC: samsung: Drop AC97 drivers
The AC97 drivers are broken and it seems these have not been used for a long time. This patch removes the unused code, i.e. Samsung SoC AC97 controller driver and related machine drivers: ln2440sbc_alc650, smdk2443_wm9710, smdk_wm9713. Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
