[PATCH] fix inline related gcc 3.4 build failures in drivers/net/wan/dscc4.c

Hi,

Here's a patch against 2.6.8-rc2-mm1 to fix up some build errors due to
function inlining failing with gcc 3.4.0


drivers/net/wan/dscc4.c: In function `dscc4_found1':
drivers/net/wan/dscc4.c:369: sorry, unimplemented: inlining failed in call to 'dscc4_set_quartz': function body not available
drivers/net/wan/dscc4.c:898: sorry, unimplemented: called from here

This one I fixed by moving the function before the point of its first use
since it's quite small.

drivers/net/wan/dscc4.c: In function `dscc4_irq':
drivers/net/wan/dscc4.c:354: sorry, unimplemented: inlining failed in call to 'dscc4_rx_irq': function body not available
drivers/net/wan/dscc4.c:1518: sorry, unimplemented: called from here
drivers/net/wan/dscc4.c:355: sorry, unimplemented: inlining failed in call to 'dscc4_tx_irq': function body not available
drivers/net/wan/dscc4.c:1525: sorry, unimplemented: called from here

These two I fixed by un-inlining them since they are both very big
functions. They are both only called from a single location though, so
maybe they should just be moved, but I took the 'un-inline' approach in
the patch below. If you want a patch to move them instead, then just let
me know. The important thing is that with this patch the build no longer
breaks.

Patch is compile tested only since I don't have the hardware, but I don't
see how this could possibly break anything as there are no behavior
changes.
