several fields.

- support both v2 and v1 style smd channels
- support both v2 and v1 smsm shared state
- update smsm state defines and smem item enum
- prep work for dealing with smd to qdsp6
- simplify some smem access to minimize use of smem_alloc() at runtime

This code provides the low level interface to the "shared memory
state machine" (smsm), and the virtual serial channels (smd), used
to communicate with the baseband processor.  Higher level transports
(rpc, ethernet, AT command channel, etc) ride on top of this.

Infrastructure to support the Qualcomm "shared memory driver"
interface, used to communicate with the baseband processor on MSM7k
SoCs.  The smd core provides low level facilities to interact with the
shared memory comms region, and a "virtual serial channel" interface
that higher level transports (AT command channel, rmnet virtual
ethernet, qmi network management protocol, and oncrpc, for example)
are routed over.
