[PATCH] agp: parisc-agp: fix section mismatch warning

[Randy Dunlap]

Fix section mismatch warning in parisc-agp:

WARNING: modpost: drivers/char/agp/parisc-agp.o(.text+0x7a0): Section mismatch in reference from the function init_module() to the function .init.text:parisc_agp_setup.isra.0()
The function init_module() references
the function __init parisc_agp_setup.isra.0().
This is often because init_module lacks a __init 
annotation or the annotation of parisc_agp_setup.isra.0 is wrong.

Fixes: 08a6436816f7 ("[PARISC] Add support for Quicksilver AGPGART")
