pxa: make it clear by converting MMC 'delay_detect' to millisecond

[ARM] pxa: make it clear by converting MMC 'delay_detect' to millisecond

delay_detect in HZ is confusing, convert it to be millisecond based. And thus remove those unnecessary call to msecs_to_jiffies() at runtime for this field. Other constants are converted assuming HZ == 100, which are basically true for those platforms.

The assignment in csb726.c was incorrect, and is fixed in this patch as a result.
