When booting up we need to wait for the modem processor to
partially boot. This is because the modem processor does
resource allocation for us. If we don't wait the modem won't
honor our requests and we end up crashing or in an unknown
state. This change just formalizes the waiting process.

"unsigned" translates to "unsigned int", but this value holds an

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.
