ASoC: rsnd: ssi: wait maximum 5ms for status check 



It is waiting udelay(50) x 1024 (= 50ms) for status check
in worst case, but it is overkill.
And we shouldn't use udelay() for 50us
(linux/Documentation/timers/timers-howto.txt)

Waiting maximum udelay(5) x 1024 (= 5ms) is very enough
for status check.
This patch fixes these issue.
