Sam Ravnborg f4e64333f8 isdn: fix section mismatch warning for ISACVer 
Fix following warnings:
WARNING: drivers/isdn/hisax/built-in.o(.text+0x19723): Section mismatch in reference from the function ISACVersion() to the variable .devinit.data:ISACVer
WARNING: drivers/isdn/hisax/built-in.o(.text+0x2005b): Section mismatch in reference from the function setup_avm_a1_pcmcia() to the function .devinit.text:setup_isac()

ISACVer were only used from function annotated __devinit
so add same annotation to ISACVer.
One af the fererencing functions missed __devinit so add it
and kill an additional warning.
