This irq handler isn't used in all cases, so add the proper ifdef. This
eliminates a compiler warning due to the function not getting used.

"unsigned" translates to "unsigned int", but this value holds an
address. We always want to use unsigned long for addresses since
it will change size to fit the machine.
This just convert the one address holder to unsigned long.

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.

Some smd clients may write from multiple threads, in which case it's
not safe to call smd_write without holding a lock. smd_write_atomic()
provides the same functionality as smd_write() but obtains the smd
lock first.

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.
