I took the liberty of updating the commit message a bit, to try to
further clarify things. Moreover, future wise, let's use the prefix,
"mmc: dw_mmc-starfive" for the commit message header, to be consistent
with the other dw_mmc drivers.

So, applied for fixes and by adding a fixes tag, thanks!

Kind regards
Uffe
