PATCH: radeondrm x86_64 and android32

[Sergey Korshunoff]

Android-x86 4.0-r1 (32 bit) have problems with x86_64 kernel when he
trying to use a radeon kms. The following change correct a problem:

drivers/gpu/drm/radeon_kms.c (function radeon_info_ioctl):

- value_ptr = (uint32_t *)((unsigned long)info->value);
+ value_ptr = (uint32_t *)((unsigned)info->value);

Looks like a userspace data in android running under x86_64 is located
above 4 Gb. I don't think so. But after this change android run fine.
