The flags field of struct resource from linux/ioport.h is "unsigned
long". Change the "type" parameter of coalesce_windows() function to
match that field. This fixes the following warning messages when
compiling with "make C=1 W=1 bzImage modules":

arch/x86/pci/acpi.c: In function ‘coalesce_windows’:
arch/x86/pci/acpi.c:198: warning: conversion to ‘long unsigned int’ from ‘int’ may change the sign of the result
arch/x86/pci/acpi.c:203: warning: conversion to ‘long unsigned int’ from ‘int’ may change the sign of the result
