tricky one: hisax sections

Browse Source 
a) hisax_init_pcmcia() needs to be defined only if we have
   CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared
   __devinit.

b) HiSax_inithardware() can go __init

c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card():
	checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card);
   The problem with it is that
	* hisax_cs_setup_card() is __devinit
	* hisax_register() is not
	* hisax_cs_setup_card() is a switch from hell, calling a lot of
	  setup_some_weirdcard() depending on card->typ.  _These_ are also
	  __devinit.

   However, in hisax_register() we have card->typ equal to
   ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind
   all that crap, just do nothing and return 2".  So we add a
   trimmed-down callback doing just that and passed to checkcard() by
   hisax_register().  _This_ is non-init (we can stand the impact on
   .text size).

Voila - no section warnings from drivers/isdn
