set_delay() has return type as void. If there are any errors while setting tapdelay's it won't be able to return them.
Change the prototype of set_delay() in sdhci_ops structure and return the errors from wherever it is called.

Changes in v2: - This is the second patch that has been split from 1/7 - This covers changes for sdhci driver separately - Added a debug print in case of error from set_delay()
