[PARISC] fix section mismatch in parisc eisa driver

Hi Kyle,

this patch fixes the following section mismatch (EISA cards should be hotplug aware, but the EISA bus itself shouldn't):
WARNING: drivers/built-in.o(.text.eisa_probe+0x220): Section mismatch: reference to .init.text:eisa_root_register (after 'eisa_probe')

Please apply,
Helge
