The end field of struct resource is unsigned long, so on 32-bit targets,
this is a 32-bit value. This results in a compiler warning of "warning:
comparison of distinct pointer types lacks a cast". Fix it by making
max_iomem unsigned long to match the end field.

Fixes: (82626363a217 "drm: add func to get max iomem address v2")
