[PATCH 1/2] drm/radeon: Using unsigned long instead of unsigned to fix possible overflow

[Hanjun Guo]

VBIOSImageOffset in struct UEFI_ACPI_VFCT is ULONG (unsigned long),
but it will be assigned to "unsigned offset", so use unsigned long
instead of unsigned for the offset, to avoid possible overflow.
