rsi: fix for sdio interface setup in 9116

Browse Source 
Issue: RS-9116 Card is not responding after firmware got loaded.

Root cause: After firmware got loaded, we need to reset the program
counter and few device specific registers. Those registers were not
resetted properly.

Fix: Properly resetting those registers.
