The MSM7x30 does not have a separate bank of memory for shared
memory communication with the radio CPU.  Set the kernel base
address 2MB in, to use this first 2MB for this purpose.

The MSM SOC's DMA controller contains several security domains.
On the MSM7x00, only security domain 3 is accessible to our CPU.
The 7x30, however, uses security domain 2.  Fix up the register
definition macros to select this appropriately, based on
configured target.

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.
