From: Ludovic Barre <ludovic.ba...@st.com>
mmci_irq function loops until the status is totally cleared.
However the busy_detect_flag could occurred even if no busy
response is expected and that busy d0 line is low (like in
cmd11: voltage switch).
Like busy_detect_flag is handled into mmci_cmd_irq this flag
can be always excluded.
