USB: musb: error out when anomaly 05000380 is applicable 



Since we can't work around anomaly 05000380, throw a build error up and
instruct the user to use a different mode.

/* The Mentor USB DMA engine on BF52x (silicon v0.0 and v0.1) seems to be

 * unstable in host mode.  This may be caused by Anomaly 05000380.  After

 * digging out the root cause, we will change this number accordingly.

 * So, need to either use silicon v0.2+ or disable DMA mode in MUSB.
