ASoC: cs42l52: Fix mask for REVID

BIT[0:2] of register 01h is REVID, so the mask for REVID should be 0x7. Also updates the code to use CS42L52_CHIP_REV_MASK. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Brian Austin <brian.austin@cirrus.com> Signed-off-by: Mark Brown <broonie@linaro.org>
