MUSB: Add sanity check for maximum number of endpoints

There is no check if platform code passes in more endpoints (num_eps)
than the maximum number of enpoints (MUSB_C_NUM_EPS.)  The result is
that allocate_instance() happily writes past the end of 'struct musb'
corrupting memory.

This patch adds a BUG() if the platform code requests more than the max.
