[PATCH] drivers/isdn/hisax/: possible cleanups

This patch contains the following possible cleanups:
- make needlessly global code static
- remove the compiled but unused st5481_hdlc.{c,h}
- kill enternow.h
- enternow_pci.c: kill InByte/OutByte/BYTE
- isdnl2.c: kill FreeSkb
- remove or #if 0 the following unused functions:
- config.c: IsdnCardState
- ipacx.c: ipacx_new_ph
- ipacx.c: dch_bh
- ipacx.c: setup_ipacx
- isdnl2.c: IsRR

-  hdlc_decode - decodes HDLC frames from a transparent bit stream.
-
-  The source buffer is scanned for valid HDLC frames looking for
-  flags (01111110) to indicate the start of a frame. If the start of
-  the frame is found, the bit stuffing is removed (0 after 5 1's).
-  When a new flag is found, the complete frame has been received
-  and the CRC is checked.
-  If a valid frame is found, the function returns the frame length 
-  excluding the CRC with the bit HDLC_END_OF_FRAME set.
-  If the beginning of a valid frame is found, the function returns
-  the length. 
-  If a framing error is found (too many 1s and not a flag) the function 
-  returns the length with the bit HDLC_FRAMING_ERROR set.
-  If a CRC error is found the function returns the length with the
-  bit HDLC_CRC_ERROR set.
-  If the frame length exceeds the destination buffer size, the function
