hostap: hide unused procfs helpers

When CONFIG_PROC_FS isn't set, gcc warning this:

drivers/net/wireless/intersil/hostap/hostap_hw.c:2901:12: warning: ‘prism2_registers_proc_show’ defined but not used [-Wunused-function]

            ^

fix this by adding #ifdef around them.
hfa384x_read_reg is only used by prism2_registers_proc_show,so move it
into #ifdef.
