[U-Boot] [PATCH] mmc: dw_mmc: set host_caps mmc modes to equivalent buswidth and lower

[Jan Havran]

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 required mode.
