Subject: [PATCH] Revert: ASoC: rsnd: ssi: wait maximum 5ms for status check
By waiting only a maximum of 5ms, we break the Renesas
ADSP firmware's ability to access the SSI directly.
This functionality is currently used by the Fiberdyne DSP.
Since we shouldn't use udelay() for 50us
(linux/Documentation/timers/timers-howto.txt), we instead increase
the loop length to 1024*10 (5ms*10=50ms).
