PCI: prepare pci=realloc for multiple options
Let the user could enable and disable with pci=realloc=on or pci=realloc=off Also 1. move variable and functions near the place they are used. 2. change macro to function 3. change related functions and variable to static and _init 4. update parameter description accordingly. This will let us add a config option to control default behavior, and still allow the user to turn off automatic reallocation if it fails on their platform until a permanent solution is found. -v2: still honor pci=realloc, and treat it as pci=realloc=on also use enum instead of ... -v3: update kernel-paramenters.txt according to Jesse.
