msm: mdss: dsi: fix panel minimum refresh rate configuration
In the current implementation, if a DSI panel does not explicitly
specify the minimum supported refresh rate, then it is set to
48 by default. This is incorrect since many panels may not support
that low of a refresh rate. Fix this by setting the default value
to the panel's actual refresh rate.
