MicroVAX1: Remove DMA devices which weren't supported on MicroVAX I

Browse Source 
Removed TQ (TMSCP), TS (TSV11) and VH (DHV11) devices from this
simulator since these devices were never supported in release MicroVAX I
configurations.

Lacking a scatter/gather map, DMA devices needed to be written to
perform DMA into contigous buffers in low memory and then copy data
to user space buffers.  The MSCP protocol devices had specific support to
do scatter/gather transfers as part of the protocol.  The RL01/RL02 device
driver was modified to perform the appropriate buffer moves most likely
to prove the customer option to adjust their drivers actually worked.  In
any case, boot support for RL01/RL02 disks does not exist.
