[PATCH 4/6] isdn/hisax: clean function declaration in hscx.c up

[Baoyou Xie]

We get 1 warning when building kernel with W=1:
drivers/isdn/hisax/hscx.c:175:1: warning: no previous prototype for 'open_hscxstate' [-Wmissing-prototypes]

In fact, this function is declared in
drivers/isdn/hisax/elsa_ser.c, but should be
declard in a header file, thus can be recognized in other file.

So this patch moves the declaration into drivers/isdn/hisax/hscx.h.
