[PATCH] drm: fix drm_get_max_iomem type mismatch

[Arnd Bergmann <arnd@arndb.de>]

When comparing two variables with min()/max(), they should be the same type:

drivers/gpu/drm/drm_memory.c: In function 'drm_get_max_iomem':
include/linux/kernel.h:821:16: error: comparison of distinct pointer types lacks a cast [-Werror]
  (void) (&max1 == &max2);

This makes the local variable in drm_get_max_iomem make the type
from resource->end.

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