ASoC: Fix mpc5200-psc-ac97 to ensure the data ready bit is cleared

Browse source

When doing register reads, it is possible for there to be a stale
data ready bit set which will cause subsequent reads to return
prematurely with incorrect data.  This patch fixes the issues by
ensuring stale data is cleared before starting another transaction.
