Staging: vme: Assure D16 cycle if required in master_read and master_write

Subject: [PATCH] Staging: vme: Assure D16 cycle if required in master_read and master_write
memcpy_fromio() and memcpy_toio() functions apply internally to __memcpy() that
performs data transfer in 32-bits or 8-bits blocks (at least on x86). This makes
impossible to perform D16 cycle with ca91cx42 bridge. Provided modification
assures performing data transfer with 32, 16, and 8 bits chunks.
