Summary: added support for the asix ax110xx chips

hi all,
 
just made a small patch to sdcc & the ds390 code to support the asix ax110xx cpu's.  
they are 8051/80390 chips. the change is to add a code sequence to the  
startup stuff that the compiler generates and a small change to the  
irq-vector generation.  
 
background: the cpu always starts in 8051 mode and needs acon=0x02 to get into ds390  
mode. since the native ds390 target generates only 390 code, the chip does not  
startup. 
 
the patch adds the switch --use-asix to insert the needed sequence and set the  
cpu in 80390 mode. 
 
it is generated against a snapshot tarball from the cvs, namely from  
sdcc-src-20071129-4972.tar.bz2 
 
maybe there is a different solutioon for that, but it works for me that way ;) 
 
hope its usefull, 
greets, 
 
chris
