mISDN: hfcmulti: use __iomem address space modifier
Impact: make use of the __iomem address space modifier, and change u_char *,
u_short * and u_int * to void *
Fix more than 30 sparse warnings of this or similar type:
drivers/isdn/hardware/mISDN/hfcmulti.c:261:31: warning: incorrect type in argument 2 (different address spaces)
drivers/isdn/hardware/mISDN/hfcmulti.c:261:31: got unsigned char [usertype] *
drivers/isdn/hardware/mISDN/hfcmulti.c:261:31: expected void volatile [noderef] <asn:2>*addr
