drm/i915: disable pci resize on 32-bit machine
PCI bar resize only works with 64 bit BAR so disable
this on 32-bit machine and resolve below compilation error:
drivers/gpu/drm/i915/gt/intel_region_lmem.c:94:23: error: result of
comparison of constant 4294967296 with expression of type
'resource_size_t' (aka 'unsigned int') is always false
[-Werror,-Wtautological-constant-out-of-range-compare]
root_res->start > 0x100000000ull)
Fixes: a91d1a17cd341 ("drm/i915: Add support for LMEM PCIe resizable bar")
