Fix paddrBits < xLen && paddrBits == vaddrBits case

Require and/or force vaddrBits to be bigger than paddrBits so there's
room to zero-extend a physical address by 1 bit, so that when the virtual
address is sign-extended, the sign is zero.

tilelink: split Acquire into Acquire{Block,Perm} ( #1030 )
...
We had planned for a while to add an 'Overwrite' message which obtains
permissions without requiring retrieval of data. This is useful whenever
a master knows it will completely replace the contents of a cache block.
Instead of calling it Overwrite, we decided to split the Acquire type.
If you AcquirePerm, you MUST Release and ProbeAck with Data.
