mmc: dw_mmc: force setup bus if active slots exist
It's necessary to setup bus if any slots are present.
- update clock after ctrl reset
- if the host has genpd node, we can guarantee the clock is
available before starting request. Otherwies, the clock register
is reset once power off the pd, and host can't output the active
clock during communication.

Fixes: df9bcc2bc0a1 ("mmc: dw_mmc: add missing codes for runtime resume")
