[PATCH] hostap: Use void *hw_priv instead of #ifdef in local data 

Replace hardware model specific #ifdef's in struct local_info with
void *hw_priv that is pointing to cs/pci/plx specific data
structure. This removes unneeded #ifdef's and as such, is a step
towards making it possible to share objects for hostap_hw.c and
hostap_download.c with cs/pci/plx drivers without having to compile
and link the same code separately for each one.
