[Qemu-devel] [PATCH v2] hw/pci-host/q35: Replace hardcoded value with macro

[Zihan Yang]

During smram region initialization some addresses are hardcoded,
replace them with macro to be more clear to readers.

Previous patch forgets about one value and exceeds the line
limit of 90 characters. The v2 breaks a few long lines
