This moves the msm_a2m_int() function into the header, and
does a small macro clean up to be more inline with Linux
norms. No functional changes.

This modifies SMD to use either the package v3 or package v4,
but not both. The current code tries to allocate as v4 on all
system which can produce a scary looking error message on boot up,
smem_find(16, 40): wrong size 16424
smd_alloc_channel() cid=02 size=08192 'SMD_RPCCALL'
With this error the code then falls back on the package v3 allocation
method. This method is inefficient because it causes a slow down
on some systems even when the allocation method can be determined
at compile time. It also causes a kernel size increase that effects
all system and is not needed.
This change corrects the allocation to use one method or the other
and not both.

Forcing the alignment prevents gcc from generating byte reads for word
member variables. Lack of this caused issues when the app processor
modified struct members and the modem saw a partial word write.

- QSD8250 has a DSP that speaks SMD, in addition to the modem
- handle a separate list of modem vs dsp channels
- install dsp smd irq handler as necessary

The new protocol require writing to two state fields, and reading
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.
