platform: msm_shared: Reduce polling interval

sdhc driver looks for command and transfer complete interrupts
with polling interval of 500 & 1000 us respectively. Instead of
this we can reduce the polling interval & increase the retry count
to improve the performance. Also fix typo to remove ';' at the end
of while loop.
