Subject: [PATCH 12/26] drivers: isdn: Mark functions as static and remove
 unused function in hfcmulti.c

Mark functions as static in hardware/mISDN/hfcmulti.c because they are
not used outside this file. Remove unused function from
hardware/mISDN/hfcmulti.c.

This eliminates the following warnings in hardware/mISDN/hfcmulti.c:

drivers/isdn/hardware/mISDN/hfcmulti.c:574:1: warning: no previous prototype for ‘disablepcibridge’ [-Wmissing-prototypes]
