dwmci_setup_cfg was clearing all modes except the mode equivalent to required bus width. Moreover, for buswidth = 1 was set the 4-bit mode.

This sets host caps to all modes from 1-bit up to the required mode.

I don't remember exactly. But when i had added this line, there was some issue. I will check again. Thanks!
